Epoxy Powder Coating Chemical Resistance

The variety of combinations of epoxy resins and reinforcements provides a wide latitude in properties obtainable in molded parts.

Epoxy powder coating chemical resistance.

The chemical cross linking for hybrids and tgic powders representing the major part of the global powder coating market is based on the reaction of organic acid groups with an epoxy functionality. Chemical 1 2 630 633. Acetone nr nr s 3 s 3. With liquid paint horizontal and vertical painted surfaces often have differences in appearances but powder coating typically provides a uniform visual appearance regardless of orientation.

Epoxy based powder coating is not recommended for exposed open air environments or situations where exposure to ultraviolet radiance will cause chalking. Gives hard durable protective finishes with excellent adhesion and chemical resistance.

The thermoset polymer coating is hard and also offers chemical resistance flexibility and high adhesion. This carboxy epoxy reaction is thoroughly investigated and well understood by addition of catalysts the conversion can be accelerated and curing schedule can be triggered in time and or temperature. Always check the chemical resistance with the epoxy manufacturer. Recommended uses include general industrial components and applications requiring a good all round coating such as household goods.
