Tokuyama REOLOSIL QS40 is a hydrophilic fumed silica imported from Japan, made by burning high-purity silicon tetrachloride in a hydrogen-oxygen flame. It has ultra-large specific surface area, high purity, strong reinforcement and excellent thixotropy, serving as a core functional additive for multiple systems.
High-purity primary preparation - Made by hydrogen-oxygen flame process, no impurity residue, high SiO₂ purity and excellent batch stability
Ultra-large specific surface area - Specific surface area up to 380±30m²/g, outstanding thickening, thixotropic and anti-settling effects, suitable for multiple systems
Multifunctional integration - Integrates reinforcement, thickening, anti-settling, thixotropy and fluidization functions to solve various processing needs in one stop
High transparency adaptability - Particle size only about 7nm, does not affect product transparency after dispersion, suitable for high-end transparent coatings and resins
Wide system compatibility - Excellent hydrophilicity, good compatibility with water-based and polar solvent systems, easy to add and disperse
Coatings and inks - Used as anti-settling agent and thixotropic agent to prevent pigment settling and improve coating uniformity and workability
Adhesives and sealants - Thicken and reinforce, optimize thixotropy, prevent sagging, and enhance bonding strength and durability
Silicone rubber and organic elastomers - Efficient reinforcement to improve product tensile, tear strength and mechanical stability
Unsaturated polyester resin (UPR) - Enhance resin strength and transparency, extend system pot life
Flowable powders - Improve powder fluidity and anti-caking, and enhance processing efficiency and storage stability
