HMDS targeted modification – uniformly treated with hexamethyldisilazane, stable hydrophobicity, hydrolysis and moisture resistance, improving long-term storage of formulas
Stable rheological control – excellent thixotropic performance, anti-sagging and anti-sedimentation, optimizing construction and molding effect of coatings and adhesives
Efficient elastomer reinforcement – as the core reinforcing filler for silicone rubber, significantly enhancing mechanical strength, toughness and aging resistance of products
Powder flow aid & anti-caking – effectively improving powder fluidity, preventing caking, optimizing powder processing and storage convenience
High purity & low impurity – high silica content and extremely low impurities, suitable for high-end transparent products and electronic related applications
Silicone rubber products – suitable for HTV, LSR and other silicone rubbers, efficiently reinforcing and improving mechanical properties and service life
Paints/inks – thixotropic anti-sagging and anti-pigment sedimentation, enhancing film flatness, scratch resistance and weatherability
Adhesives/sealants – optimizing rheological properties and bonding strength, enhancing long-term waterproof sealing reliability
Powder coatings/toners – flow aid and anti-caking, improving powder processability and finished product appearance quality
Industrial defoaming systems – relying on strong hydrophobicity to improve defoaming efficiency and long-term stability, suitable for various defoaming scenarios
