The gloss level ranging from 7 to 50 can be easily obtained by adjustment of formulation. The minimum baking temperature for consistent gloss and mechanical properties starts from 170℃.
Appearance：white or yellowish powder
Melting point ：not applicable
Dosage: typically 1-5 percent based on total formulation.
