Calcium sulphate fiber has high whiteness and can replace titanium dioxide and calcium silicate in powder coatings to reduce costs.
Calcium Sulphate fiber has stable chemical properties, acid and alkali resistance, and high temperature resistance. The prepared powder polyester coating has a working temperature of 300 ℃, strong adhesion, hardness and good gloss.
Excellent dispersion and fluidity , can improve powder film properties and powder fluidity.
The raw material of gypsum fiber is food-grade gypsum ore, which does not contain heavy metals and halogens. It is an environmentally friendly material.
Scope of application: suitable for white powder coatings with gloss below 85 degrees.

Proportion of Fibrous Calcium Sulphate : 3-8% of percentage of grits or grits +fillers.
Formula amending and improving advise: Calcium Sulphate can substitutes of Cryolite, Barite, Alumina and Resin powder percentage partially. It just depends on different formulations.
Advised methods for blending/pre-blending: Can be mixed with abrasives, fillers. Can be mixed with resins liquid, be appropriate to longer mixing time to ensure blending evenly.
Preservation: water-proof, moisture-proof. Use as soon as possible after opening after opening the bag.
