Tokuyama REOLOSIL DM-30S is a hydrophobic fumed silica imported from Japan, surface-modified with dimethyldichlorosilane. It has high specific surface area, strong thixotropy and excellent reinforcement, designed for polar liquid systems, suitable for paints, inks, silicone rubber and other fields.
Strong hydrophobicity & moisture resistance – organically modified surface, hydrolysis-resistant, prolong formula storage stability
High specific surface area reinforcement – ultra-fine particle structure, greatly enhance mechanical strength of silicone rubber
Strong thixotropic thickening – quickly form 3D network, prevent sagging and sedimentation, improve construction fluency
Ultra-high purity – extremely low metal ions, suitable for high-cleanliness scenarios like LED and toner
Multi-scenario adaptability – flow aid and anti-caking functions, suitable for powder and liquid system
Paints & coatings – thickening and anti-settling for polar systems, improve film flatness and weatherability
Printing inks – enhance thixotropy and pigment dispersion, improve printing clarity and color stability
Sealants & adhesives – thickening and reinforcement, improve bonding strength and waterproof performance
LED & electronic materials – high purity for encapsulation, ensure insulation and electronic stability
Toner & powder materials – flow aid and anti-caking, adjust charging performance, improve processing effect
