Powder Surface Coating Additives

Powder Surface Modifying Agent
I. Basic performance and application
Surface modifying agent T316 surface modifying agent can increase the coat levelness and compactness, relieve orange peel, eliminate pinhole, obviously enhance the plate surface smoothness, remove the coat surface mist, greatly increase the brightness and effectively improve the coat film surface glossiness. Surface modifying agent T316, as a surface active substance, can be applicable to the production of various thermoset powders.
