 Features:

 It is a kind of hydrophilic and high purity white colloidal powder. Due to its small particle size, specific surface area is big, therefore has excellent surface adsorption power, good dispersion performance, and good heat resistance, etc., With its excellent properties, it can be used as reinforcing filler in elastomers, excipient and carrier, rheology and thixotropic control of liquid systems, binders, polymers, etc. And used as anti-setting, thickening, anti-sagging agent, improvement of free flow and anti-caking characteristics of powders.

Application:

HTV and RTV silicone rubber\ Anti-foamer\Silicone grease\Silicone Emulsion Printing ink, Coatings, Paints \ Adhesives and Sealants OPzV\Food\Cosmetics\Medicine\Fertilizer.

Storage
