Epoxy Resin Powder Coating
Made mainly from epoxy resin which exhibits properties like excellent chemical resistance and mech-anicalness, and it is applicable to spray of metalwork that has the higher requirement of erosion resistance, electric insulativity, and pliability.
Product series
We offer standard type and cryogenic curing powder coating products. Different gloss types can be achieved, such as high gloss (above 80 percent), half gloss (50-80 percent), sub-gloss (20-50 percent), and the matt. Clients can choose surface finishing freely.
Physical characteristics of the powder

Notes | 1. In the above tests, 0.8 millimeter-thick cold-rolled derusting and degreasing steel sheet are used, and the coat thickness is 50-70 micron. | ||
2. The above performance indexes of coat may be changed with the color and reflet. |
