    Used as thickening, thixotropic, reinforcement in RTV silicone rubber
    Rheology control of adhesive
    Used as anti-settling, thickening, anti-sagging agent in coatings, inks
    Improvement of free flow and anti-caking characteristics of powders
  • 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
