KOTAMITE is a coated fine ground natural calcium carbonate
The coating of KOTAMITE is non-water wetting (hydrophobic) offering specific advantages for oil or other non-aqueous compounds.
The lubricity of the coating aids in its easy dispersion into the resin matrix and the development of low melt viscosity for thermoplastic compounds, particularly rigid and flexible PVC. |
