This product is a hydrophobic type of aerogel silica obtained by treating hydrophilic aerogel silica with dimethyl diisocyanate (DDS). It is widely used in industries such as room temperature vulcanized silicone rubber (RTV), MS glue, adhesives, sealants, cosmetics, coatings, catalysts, inks, toner and powder coatings. As a thickening thixotropic agent and reinforcing agent for room temperature vulcanized silicone rubber (RTV), its hydrophobic property gives room temperature vulcanized silicone rubber (RTV) a good shelf life.
