Differences in the Use of Different Functional Powder Coatings

1) Heat resistant powder coatings:

Heat resistant powder coating is a kind of powder coating which can resist the temperature above 200 ℃ for a long time, has good coating and can make the object under maintenance work normally in high temperature environment. According to the mechanism of thermal stability of polymer, the heat resistance of polymer mainly depends on its molecular structure. Therefore, the thermal stability of the polymer can be improved by introducing larger or more side groups into the main chain to increase the intermolecular interaction. Another way to improve the heat resistance of powder coatings is to take part in heat resistant pigments and fillers in polymers. Commonly used pigments and fillers are aluminum powder, mica powder, stainless steel powder, cadmium powder, silicon dioxide, etc.

2) Insulating powder coating:

Insulating powder coating is a kind of special coating used for motor, electronic and electrical components. Besides the maintenance and decoration performance of ordinary powder coating, it also has good electrical insulation performance. Epoxy resin is the best raw material for insulating powder coatings. It can adjust the curing speed by changing the type of curing agent, or adding special modifier and filler with excellent insulation and heat resistance, to obtain a variety of coatings from very soft, elastic to very hard and wear-resistant, so as to adapt to the application under different insulation conditions.
