Frequently Asked Questions
Stearic acid coating creates a hydrophobic surface that improves polymer compatibility, reduces moisture absorption, enhances dispersion, and improves mechanical properties of the final product.
Choose coated calcite for high-performance polymers, cable applications, automotive parts, and any application requiring superior dispersion and moisture resistance.
Coated calcite reduces processing time, lowers energy consumption, improves flow properties, and reduces wear on processing equipment due to better dispersion.
Cable & wire manufacturing, automotive plastics, high-performance polymers, and premium paint applications benefit most from coated calcite powder.
