Performance: White powder.

 

Features:Glass powder is a kind of transparent powder which is easy to polish and resist high scratch, with small particle size, good dispersion and high transparency.After many surface improvements, it has good affinity and strong steric hindrance, can be easily dispersed in the coating, and can increase the fullness of the coating after film formation. The crystal transparent primer class not only maintains the transparency of the varnish, but also provides good polishing.
