Powder Coating of Epoxy/Polyester Mixed type

＃General introductions
It is mainly made from raw material of epoxy resin and polyester resin. In the meanwhile, it has both nuique functions respectively that make the film coating with
optimal ornamental, mechanical features and better erosion resistance. It is applicable to various coating of indoor metalwork.

＃Product Series
We can offer standard type and cryogenic curing powder coating products. It can produce the product of high gloss ( above 80 percent ), half gloss ( 50-80 percent ),
sub-gloss ( 20-50 percent ), and the matt. The gloss can also be controlled by the requi-rement of consumers.

＃Physical characteristics of the powder
Proportion ( 25。C.g/cm3 ): 1.4-1.7
Particle-size distribution: 100 percent lower 100 micron ( it can be adjusted according
to particular requirement of painting )

＃Curing conditions
standard 180。C ( work piece temperature ), 15 minutes
cryogenic 160。C ( work piece temperature ), 15 minutes

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.
