Thermostability Powder Coatings

Thermostability powder coatings boast not only the properties of common powder coatings, but also the properties of heat resistance, anti corrosion, anti weathering, withstanding temperature above 350, without yellowing, cracking. The powder coatings are save, environment friendly, protect commodities with high usage, widely used in powder transformer stations, metallurgy, oil, aviation, chemical, medical, food industries, coating commodities such as oven, fans, light lanterns, heat radiator, hot air oven, dryer, flue gas pipes, chimney etc.

Confine of application:

flue gas channel;

•BBQ grill;

•heating channel;

•lantern decoration;

•dryer, etc.


Our aluminum profile designated powder coatings are of super color retention ability, can be used in hostile environment, with anti-cracking, anti-fading, color and gloss retention ability.


These series of powder coatings surpass China or international criteria:

•AAMA2604-02(American Architectural Manufacturers Association) ;

•(Britain Aluminum Profile Standard) BS 6496

••(Britain Galvanized Steel Standard) BS 64971

•China Aluminum Profile Standard) GB5237.4
