Tokuyama REOLOSIL KS-20SC is a hydrophobic fumed silica imported from Japan, surface-modified with special organosilane. It has strong thixotropy, anti-sedimentation, reinforcement and flow aid, with excellent dispersibility and compatibility, suitable for high-end applications in various fields.
Strong hydrophobicity & hydrolysis resistance – specially organo-modified, moisture-proof and hydrolysis-resistant, greatly improve long-term storage stability
Efficient thixotropy & anti-sedimentation – rely on nano-level agglomeration structure, thicken quickly and endow stable thixotropy, prevent sagging and pigment settling
Strong reinforcement & toughening – as core reinforcing filler for rubber and elastomers, significantly enhance mechanical strength, tear resistance and aging resistance
Powder flow aid & anti-caking – effectively improve powder fluidity, prevent caking, optimize powder processing and storage convenience
High purity & easy processing – ultra-fine particles (5-50nm), fluffy without agglomeration, easy to add and compatible with multiple processes
Paints & coatings – thickening and thixotropy, anti-pigment sedimentation, improve film flatness, weatherability and corrosion resistance
Printing inks – stabilize system rheology, improve pigment dispersion, enhance printing clarity and color stability
Sealants & adhesives – thickening and reinforcement, improve bonding strength, waterproof performance and long-term reliability
LED & electronic materials – high purity for encapsulation, ensure insulation performance and long-term stability of electronic devices
Silicone rubber/elastomers – efficient reinforcement, improve product toughness and wear resistance, suitable for high-end rubber products
