WACKER HDK V15A is a hydrophilic fumed silica (400±40 m²/g BET) for water-based systems, offering superior thickening and thixotropy. It enhances HTV silicone rubber reinforcement and maintains transparency in unsaturated polyesters, ideal for coatings, adhesives, and cosmetics
High Surface Area: 400±40 m²/g BET for optimal rheology control
Transparency: Low haze (<1%) in resin systems
Silicone Reinforcement: Increases HTV rubber tensile strength by 35%
Water Compatibility: Stable in aqueous formulations (pH 3.8-4.3)
Thermal Resistance: Performs up to 300°C in cured systems
Coatings: Anti-settling agent in solvent-based paints
Silicone Products: HTV/LSR rubber filler
Adhesives: Viscosity stabilizer for PVC hot melts
Inks: Rheology modifier for printing ink
