Overview
HJSIL R110 is a hydrophobic fumed silica treated with polydimethylsiloxane (PDMS), supplied as a high-purity white colloidal powder with a BET surface area of 100 ± 20 m²/g. Its hydrophobic surface provides thickening, thixotropy, reinforcement, anti-settling, anti-caking, anti-blocking, adsorption, and insulation properties across adhesives, sealants, coatings, cable gels, and toner applications.
