Overview
HJSIL R110H is a hydrophobic fumed silica treated with PDMS (polydimethylsiloxane), supplied as a high-purity white colloidal powder with a BET surface area of 190 ± 20 m²/g. As the higher-BET variant of HJSIL R110, it delivers enhanced thickening efficiency while maintaining full PDMS compatibility. Its higher surface area makes it particularly effective as a thixotropic and anti-settling agent in complex polar liquid systems. Equivalent to Aerosil R202/R208.
