WACKER HDK T30 is a hydrophilic fumed silica (270-330 m²/g BET) for coatings and silicones, providing superior thickening and thixotropy in water-based systems. It enhances HTV rubber reinforcement and maintains clarity in unsaturated polyesters, ideal for industrial formulations
Surface Area: 270-330 m²/g (DIN ISO 9277) for precise rheology control
Transparency: <1% haze in resin systems
Reinforcement: Increases HTV silicone tensile strength by 30%
pH Stability: 3.8-4.3 in 4% aqueous dispersion (DIN EN ISO 787-9)
Low Moisture: <1.5% water content (105°C)
Industrial Coatings: Anti-settling agent for epoxy/polyurethane paints
Silicone Rubber: Filler for HTV/LSR rubber
Adhesives: Thixotropy modifier in PVC hot melts
Inks: Rheology adjuster for printing inks
