The above tests all use 0.8mm degreased and rusted cold-rolled steel plates, the coating thickness is 60-80um, and the performance indicators of the coating will vary slightly with the gloss.

This product does not contain arsenic, selenium, lead, hexavalent chromium, mercury, antimony, cadmium, and other heavy metals, and complies with RoHS requirements.

Storage conditions: Store in a dry, ventilated room at around 25C, avoid direct sunlight. Under this condition, the powder can be stored for 6-12 months. If it exceeds the expiration date, it can be re-tested. If the results meet the requirements, it can still be used.

Advanced Surface Protection for Metal Applications

Polyurethane powder coatings are designed to safeguard and beautify metal surfaces used in both architectural and industrial settings. With a wide color range and finish options, our coatings offer excellent UV, weather, and chemical resistance. The coatings cure rapidly at 160-200C and provide durable finishes for a variety of decorative or protective uses. These powders are supplied in easy-to-handle packaging with long shelf stability, making them well-suited to both large and small application projects.


Effortless Application and Versatility

Polyurethane powder coatings are straightforward to apply using methods such as electrostatic spray or fluidized bed. They form hard, protective, and aesthetically appealing layers with excellent adhesion and consistent film thickness. Suitable for both indoor and outdoor applications, the coatings maintain their performance and vibrant appearance even under challenging environmental conditions. Their non-toxic formulation ensures safety during handling and application, affording peace of mind for operators and end users alike.
