HBF-620 hydrophobic fumed silica

Description

HBF-620 is a hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific surface area of 200m2 /g after chemical post-treatment with HMDS (Hexamethyldisilazane).

Features
• Hydrophobic component for reinforcement in HTV silicone rubber and liquid silicone rubber (LSR)
• Water resistant, hydrophobising of liquid system
• Rheology control of complex liquid system
• Small particle size and good dispersion endow the defoamer with good defoaming ability
• Improvement and maintenance of free flow and anti-caking characteristics for powders

Technical Data

Application
