Description


Zinc stearate is used in the pharmaceutical industry and the cosmetic products like face powder to improve the smoothness and adhesion. It is used in paint industry as a gloss imparting agent and a grinding agent. In plastic and rubber processing, zinc stearate is ued as a releasing agent and lubricant which can be easily incorporated. It is used as as a metal release agent in rubber, polyurethane and polyester processing system.


Applications


The film-forming substances of NC are mainly cellulose nitrate (nitrocellulose)and alkyd resin.NC is natural drying coating which is characterized by a dry-speed quickly. Because the big molecular weight of cellulose nitrate and the low solid content of NC, its wettability for powder is poor. Therefore, appropriate addition of zinc stearate is 1%to 2%in NC, adding overload will affect the

adhesion and transparency of the primer.
