RS-50 is effective as a thickening and thixotropic rheology control agent in many polymer systems, such as adhesives, coatings, sealants, printing inks, unsaturated polyesters, cosmetics, etc. It can be used as an active reinforcing filler in elastomers and silicone-elastomers. RS-50 is also effective as a flow aid additive in the production of industrial mineral powders.
