High Hydrophobicity And Stable Thixotropy Fumed Silica Powder Used For HTV Silicone Rubber
HB-615 is a hydrophobic fumed silica after treated with DDS (Dimethyl based on a hydrophilic fume silica with a specific surface area of 120 m2/g. It is a kind of high purity white colloidal powder.
1, HTV Silicone Rubber, Elastomeric, SLR
2, Adhesive and Sealants
3, Coatings, Inks.
4, Powder Coatings
5, Negative Toners
1, Reinforcement in elastomeric, can effective prevent from the structurization and prolong the shelf-life of RTV silicone sealants.
2, High Hydrophobicity and stable thixotropy, using in coating and ink can prevent from anti-caking, anti-sagging, anti-thixotrophy.
3, High Hydrophobicity and rheology in Adhensives and Sealants.
4, Improve the homogeneity and stability of pigment.
5, Improve the free flow of powder coating and anti-caking.
