HJSIL® R274 Hydrophobic Fumed Silica
HJSIL® R274 is a kind of hydrophobic fumed silica, treated with DDS (Dimethyldichloro-silane). It’s high purity white colloidal powder. Reinforcement in elastomer, can effective prevent from structurization and prolong the shelf-life of RTV silicone sealants
High hydrophobicity and stable thixotropy, using in coating and ink can prevent from anti-caking, anti-sagging and anti-thixotrophy
High hydrophobicity and rheology in adhesives and sealants
Improve the homoeneity and stability of pigment
Improve the free flow of power coating and anti-caking
