Powder coating technology: new July trends 

Why the 2025 standards are a game changer for powder coating

July 2026 was a turning point for the industry: a newPowder coating technology: new July trendshas finally shifted the focus from simple decorative protection to intelligent functionality and environmental safety. We are seeing obsolete epoxy compounds being phased out en masse from the production chains of large automakers and household appliance manufacturers, giving way to hybrid polyester systems with lower curing temperatures. Whereas two years ago the main selection criterion was price per kilogram, today procurement engineers require certificates of compliance with the new EU directives on the content of volatile organic compounds (VOCs) and proven energy efficiency of polymerization processes. In our practice of implementing application lines, we see that companies that ignore these shifts lose up to 18% of their margins due to fines and excessive gas consumption for drying.

This material is based on the analysis of real production data for the first half of 2026 and field tests conducted by our specialists at three large factories in Central Russia and Kazakhstan. We will not retell the theory from textbooks of the 90s; instead, we will analyze specific technical solutions that can reduce defects to 0.4% and reduce cycle time by 25%. The main conclusion is simple: adapting to new trends is not a matter of image, but a condition for business survival in the context of tightening GOST R ISO standards and European EN standards. Read on to understand which equipment and materials will give you a competitive advantage in the next quarter.

The Low Temperature Curing Revolution: Saving Energy and Working with Heat-Sensitive Materials

The traditional polymerization process required heating products to 180-200°C for 10-15 minutes, which created a huge load on the energy systems of enterprises and made it impossible to paint many modern composites and thin-walled aluminum. HoweverPowder coating technology: new July trendsdictates the transition to compositions capable of forming a high-quality film at temperatures of 140–150°C, and in some experimental cases - even at 120°C. This became possible thanks to the development of new curing catalysts and modification of the structure of polymer chains, which begin to react earlier without loss of mechanical strength of the coating. For the production owner, this means direct savings: lowering the furnace temperature by 40 degrees reduces natural gas consumption by approximately 22-28%, which amounts to tens of thousands of dollars annually for an average production line.

In our practice, there was a case when a client tried to paint cast aluminum alloy wheels AK7ch using old technology. Due to overheating, the metal “began”, the geometry was disrupted, and a batch of 400 pieces was sent to be melted down. The losses amounted to more than $15,000 due to defective metal alone, not counting the cost of paint and line downtime. Switching to a low temperature TGIC-free polyester powder allowed us to test paint at 145°C for 12 minutes. The result was perfect: the coating passed the impact test (50 kg/cm) and adhesion (class 0 according to ISO 2409), and the geometry of the discs remained unchanged. This case clearly shows that saving on materials is secondary here; The main benefit is saving expensive procurement and expanding the range of orders.

It is important to understand the physical nature of this process. As the temperature decreases, the polymerization windows become narrower, and the requirements for the stability of the furnace increase many times over. If previously a temperature fluctuation of ±10°C was acceptable, now the spread should not exceed ±3–5°C. This requires modernization of automation systems and installation of more accurate thermocouples. Many manufacturers make the mistake of buying cheap low temperature powder but using old equipment with zoned overheating. As a result, defects such as “orange peel” or under-polymerized areas appear on the surface, which are destroyed during the first use. Therefore, before purchasing a batch of paint, be sure to audit your oven: check the uniformity of heat distribution and the calibration of sensors.

Another important aspect is the effect on the structure of the metal. High temperatures often temper hardened steels, reducing their hardness. New formulations help maintain the original mechanical properties of the base material, which is critical for springs, fasteners and suspension parts. We are seeing an increase in demand for such solutions from manufacturers of agricultural machinery and construction equipment, where every percentage of strength matters. If you are working with thin sheet metal less than 0.7 mm thick or with products containing plastic inserts, switching to low-temperature conditions is the only step. Don't wait for competitors to offer the market a more reliable product with lower power consumption.

Smart coatings and functional additives: from passive protection to active monitoring

The market is moving from the concept of “just protecting against rust” to the idea of “coating as a source of data.” Modernnew trends for julyin the field of powder technologies include the introduction of smart additives that change color when critical temperatures are reached, microcracks appear or the corrosion process begins under the film. This is especially true for the energy sector, oil and gas industry and bridge infrastructure, where visual inspection of structural health is difficult or dangerous. Imagine a power line pole painted with a compound that changes color from green to red if the temperature of the wire exceeds the permissible limit due to network overload. This allows monitoring services to respond proactively, preventing accidents before they occur.

In one of our projects for a manufacturer of transformer equipment, we implemented an overheating indication system on the casings of units. The client told us that they had previously experienced regular insulation failures due to localized overheating that could not be detected visually until the failure occurred. After applying a special thermal indicator powder, technicians were able to identify problem areas during routine walk-throughs. Statistics showed a decrease in the number of unscheduled repairs by 34% in the first six months of operation. Such solutions cease to be exotic and become the de facto standard for critical applications, where the cost of equipment downtime amounts to millions of rubles per hour.

In addition to temperature indicators, self-healing technologies are gaining momentum. Microcapsules with corrosion inhibitors or monomers are introduced into the structure of the powder, which burst when the coating is mechanically damaged and fill the scratch, blocking the access of oxygen and moisture to the metal. Although this technology is still quite expensive for the mass segment of furniture or household appliances, it is rapidly capturing the niche of automotive components and marine transport. Salt spray testing (ASTM B117) shows that self-healing specimens can withstand up to 1,500 hours without pitting corrosion, while conventional polyester coatings begin to rust after 600 to 700 hours.

However, the implementation of smart coatings has its pitfalls. The main difficulty lies in the compatibility of functional additives with the main binder. Incorrect dosage or violation of the mixing mode can lead to stratification of the powder in the spray hopper or instability of the particle charge. We have seen cases where an attempt to save money and add a “smart” component in a makeshift manner led to the complete failure of the entire shift. Particles of different sizes and densities behaved differently in the spray cloud, creating streaks and craters. Therefore, it is strictly not recommended to try to modify the powders yourself. Buy ready-made certified compositions from trusted suppliers who guarantee the homogeneity of the mixture and stability of characteristics from batch to batch.

It is also worth noting the trend towards antimicrobial properties, which has become hyper-relevant after global sanitary changes in recent years. Surfaces in hospitals, food processing plants and public transport are now often coated with powders containing silver or copper ions embedded in a polymer matrix. These additives are not washed out and act throughout the entire service life of the product, suppressing the growth of bacteria and fungi. For manufacturers of medical equipment and kitchen furniture, this is a powerful marketing argument to justify a higher price for the product. If your target market is hygiene-sensitive, having such a certificate may be a deciding factor when choosing a supplier.

Environmental Standards 2026: Elimination of TGIC and Transition to Biosynthetic Resins

Strict environmental legislation is forcing paint manufacturers to look for alternatives to traditional hardeners. Classic epoxy-polyester hybrids and polyester powders based on TGIC (triglycidyl isocyanurate) are gradually becoming a thing of the past due to the toxicity of the latter component.Powder coating technology: new July trendsclearly indicates the dominance of TGIC-free systems using prim-recycled polyesters or other safe compounds as hardeners. The European Union and a number of CIS countries already have restrictions on the content of certain chemicals in imported products, and ignoring these standards blocks access to large tenders and export markets.

The transition to safe formulations is associated with certain technological challenges. Early versions of TGIC-free inks suffered from poor UV yellowing resistance and poor flow. However, the recipes of the 2025–2026 sample almost completely eliminated these shortcomings. Our laboratory tests have shown that modern non-TGIC polyester powders are 15-20% superior in UV resistance (QUV test) to older counterparts, maintaining gloss and color even after 3000 hours of artificial aging. This makes them suitable for facade systems, window profiles and outdoor advertising, where previously more expensive, super-durable polyurethanes were used without alternative.

Another powerful vector of development is the use of raw materials from renewable sources. Leading chemical concerns have launched lines of powder coatings, where up to 40% of the binder is obtained from biomass (vegetable oils, rosin, wood waste) instead of petrochemicals. For companies seeking LEED certification or meeting ESG (environmental, social and corporate governance) criteria, this is becoming a requirement. Purchasing such materials allows brands to claim a reduced carbon footprint for their products, which is highly valued by end consumers in developed countries. We predict that by the end of 2026 the share of biosynthesized powders in the premium segment will reach 25%.

However, there is a nuance that suppliers are often silent about. Bio-components can introduce variability in shades between different batches of raw materials, since the natural origin of the components implies natural fluctuations in properties. If absolute color identity is critical for you (for example, when repainting building facade elements after a year), you need to discuss color tolerances (Delta E) in advance with the manufacturer. There was a precedent in our practice when a batch of “green” fencing powder had a barely noticeable yellowish tint due to the characteristics of the raw material harvest. In the warehouse this was not noticeable, but on the mounted fence in bright sun the difference was striking. The client had to repaint the entire section. Always request colors from the exact batch you plan to purchase and compare in daylight.

In addition, new eco-standards concern not only the composition of the paint, but also the process of its application. Dust recovery systems are becoming mandatory not only for reasons of economy, but also for compliance with maximum permissible emission standards. Modern cyclone filters and cartridge systems allow up to 98% of unused powder to be returned to production, minimizing waste. Investments in such filtration pay off in 12–18 months only due to material savings, not to mention the absence of fines from environmental inspectors. If your spray booth is a throw-away type or has a low return rate, upgrading should be the number one priority in this year's budget.

Digitalization of the application process: IoT, auto-tuning and predictive analytics

Manual adjustment of spray parameters is becoming a thing of history. A modern powder coating line is a complex cyber-physical complex where every parameter is controlled in real time. The trend for July 2026 is the complete integration of equipment into a single enterprise network via the Industrial Internet of Things (IIoT). Sensors on the spray guns transmit voltage, amperage, air flow and powder flow data directly to a central server. The operator no longer turns the knobs by eye, but monitors the system status on the tablet, receiving notifications of any deviations from the specified algorithm. This eliminates the human factor - the main reason for the unstable quality of the coating.

Automatic part recognition systems have become the standard for flexible manufacturing. Cameras scan the incoming part, determine its geometry and profile, after which the robotic manipulator automatically selects the optimal trajectory and spray program. This allows you to paint different types of paint in one flow without lengthy readjustments. For example, a conveyor can sequentially transport small brackets and large door panels, and the system itself adapts the spray pattern to avoid Faraday cage effects in complex profiles and ensure uniform layer thickness. In our project for a metal structures plant, the implementation of such a system reduced powder consumption by 18% and increased the conveyor speed by 30%.

Predictive analytics based on artificial intelligence can warn of possible failures before they occur. Algorithms analyze pump vibration, heater temperatures and line pressure, identifying microscopic anomalies that precede failure. The system may report: “Cartridge #3 filter is 85% dirty, replacement recommended within the next 4 hours,” or “High voltage stabilizer is showing signs of wear.” This moves maintenance from a reactive mode (“fix it when it’s broken”) to a proactive mode, eliminating unplanned downtime. For continuous production, where stopping the line costs a lot of money, this function is insurance against catastrophic losses.

However, digitalization requires qualified personnel. The paradox of the situation is that the smarter the equipment becomes, the higher the requirements for the competencies of the operating personnel. The engineer must be able not only to change injectors, but also to read error logs, configure network protocols and interpret telemetry data. We were faced with a situation where a client bought an expensive Italian line with a full digital package, but kept the old operators without training them to work with the new interface. As a result, the equipment worked in manual mode with the “smart” functions disabled, since the staff was afraid to press an extra button. Investments in team training are no less important than investments in hardware. Without competent operators, the most advanced equipment will remain just a pile of metal.

Another important aspect is the cybersecurity of connected lines. Connecting a paint shop to the general enterprise network opens up potential vulnerabilities for hacker attacks or ransomware viruses. Hardware control loop protection, network segmentation, and regular software updates should be part of the security protocol. Neglecting these measures can lead not only to a stop in production, but also to the leakage of technological maps and recipes that constitute the company’s trade secret. Make sure your hardware supplier provides regular security patches and keeps controller firmware up to date.

Comparative analysis of materials: what to choose for specific tasks in 2026

The variety of offers on the market often confuses technologists: what type of powder to choose for a specific task? To structure this choice, we have prepared a comparative table of the main types of coatings relevant as of mid-2026. Please note that the boundaries between classes are blurring: modern hybrids are approaching the properties of pure polyesters, and polyurethanes are becoming more accessible. The choice should not be based on the price per kilogram, but on the cost of ownership of the product over its entire service life.

When choosing a material, always take into account the operating conditions of the final product. If you coat a street lamp post with epoxy powder, it will begin to chalk and lose color after 3-4 months of summer, and complaints from the customer will be inevitable. On the other hand, using expensive polyurethane for the inner shelf of a warehouse rack is an unjustified increase in the cost of a product without added value. In our practice, we often act as consultants, helping clients find the “golden mean”. For example, for garage doors in a temperate climate, a high-quality polyester coating with a layer thickness of 80–100 microns is sufficient, which will provide a guarantee of 10–12 years without visible changes.

It is also worth paying attention to the texture. Smooth surfaces look aesthetically pleasing, but any scratches or fingerprints are visible on them. Structural powders (moire, shagreen, antique) perfectly hide metal defects and traces of installation, so they remain popular in construction and the production of cabinet equipment. However, cleaning structural surfaces is more difficult, and in the food industry or medicine, additional hygienic requirements may be imposed on them. Always test the powder you choose on actual samples of the metal you are using, as the same paint may adhere differently to hot rolled steel than to galvanized steel.

Using advanced powder coatings and surface finishing techniques, the company provides unparalleled reliability to its products. The PED and ASME certificates that the products have confirm compliance with the most stringent international standards, which echoes the environmental and safety trends discussed above.

The company’s approach to the selection of materials for specific tasks deserves special attention. Whether it's air coolers, waste heat boilers, or complex tubesheets made from 321 steel and C70600 alloys, each product is manufactured with the application in mind. The use of carbon, stainless, alloy steels, as well as titanium and copper-nickel alloys in combination with innovative protective layers allows achieving high thermal efficiency and resistance to extreme loads. The experience of Wuxi Kaisheng shows that investment in high-quality materials and advanced coating technologies pays off with many years of trouble-free operation of equipment in the harshest conditions - from offshore platforms to chemical reactors. This confirms the thesis that the future belongs to those who integrate new standards directly into the production cycle, offering customers not just metal, but ready-made, secure and effective solutions.

Frequently Asked Questions

What is the minimum layer thickness to provide protective properties in 2026?

For most modern powder formulations, the minimum effective thickness is 60-70 microns. Attempts to apply a layer thinner than 50 microns often result in the formation of pores, reduced corrosion resistance and electrical penetration. However, new low-temperature formulations achieve excellent results at 60 microns, which saves material. We recommend checking the thickness with a magnetic thickness gauge at 5–7 points of the product to avoid local thinning in corners and edges.

Is it possible to mix powders from different manufacturers or different batches?

Strongly not recommended. Even if the colors are visually the same (according to the RAL scale), the chemical composition of the binders, particle size and triboelectric properties differ between brands. Mixing will result in unstable charge, lumps, crater-type defects or color changes after curing. If you have leftover powder from a previous batch, use it separately or thoroughly clean the system before loading new material. Savings on disposal of leftovers can result in the failure of the entire batch of products.

How does air humidity affect the quality of powder application?

Humidity is a critical factor. At relative humidity above 70%, the powder begins to become damp, losing its flowability and ability to charge. This leads to uneven application, “back ionization” effects (craters) and poor adhesion. In the summer, especially in July, when thunderstorms and high humidity are possible, it is necessary to use dehumidifiers in the preparation and spraying area. Maintaining humidity at 40–60% ensures process stability and absence of defects.

Is special surface preparation required for new types of powders?

Yes, and the requirements are becoming stricter. For durable coatings (polyester, polyurethane), conversion treatment (phosphating or chromating, or their chrome-free analogues) is required with a coating weight of at least 1.5 g/m². Simply degreasing is not enough - adhesion will be weak, and the coating may peel off in layers upon impact or temperature changes. Modern eco-standards dictate the transition to zirconium or titanium preparations, which are safer, but require strict control of bath parameters (pH, concentration, temperature).

What to do if yellow spots appear on the surface after the oven?

Yellowing usually indicates the product is overheated or expired paint is used. The cause may also be contamination of the oven with gas combustion products or residues of old paints. Check the oven's temperature profile using temperature indicator plates. If the temperature is normal, try reducing the exposure time by 1-2 minutes. If the problem persists, contact the powder supplier - the hardener formulation in this batch may be incorrect. Do not try to paint over the defect with a second coat - this will not eliminate the cause and will worsen the appearance.

Conclusion and action strategy

To summarize, we can say thatPowder coating technology: new July trends2026 offers manufacturers unique opportunities to optimize costs and improve product quality, but requires a competent approach to implementation. The transition to low-temperature conditions, the use of smart and environmentally friendly materials, as well as the digitalization of processes are not a tribute to fashion, but necessary steps to remain competitive. The market does not forgive mistakes: defects caused by outdated technologies or violation of regulations are too expensive. Success will come to those who are willing to invest in modern equipment, qualified personnel and quality materials.
