Paints and coatings

HTV- and LSR (Liquid Silicone Rubber)

Cable compounds and unsaturated polyester resins

Adhesives and sealants

Printing inks

Cosmetics


Properties:


Rheology and thixotropy control of liquids, binders, polymers, etc.

Optimal dispersion yields best results in pronounced thickening and thixotropy

Reinforcement of HTV- and LSR (Liquid Silicone Rubber) at a high transparency level

Excellent transparency in unsaturated polyester resins
