Characteristics
HIFULL HB-152D is hydrophobic fumed silica which is produced by HL-200 after chemical post-treatment with dimethylsilane.(DDS-Treated)
Applications
Organic silicone rubber and sealants ( HTV, RTV);
Paints, Coatings & Toner;
Adhesives;
Cosmetics
Properties & Functions
※ Perform good reinforce, thickening and thixotropic properties in RTV & other adhesive products, can improve storage stability for organic silicone sealants;
※ Uses as rheology control agent in (composite) liquid system;
※ Anti-sagging, anti-corrosion in coatings, and improve stability of pigment;
※ Improve hydrophobic and rheological performance in offset printing ink;
※ Promote and keep free flow and anti-caking properties for powders;
※ Larger specific surface area, better thickening, thixotropic and transparent properties.
