Cabot CAB-O-SIL TS720 is a hydrophobic fumed silica imported from the USA, professionally modified with polydimethylsiloxane. As a medium-surface-area functional additive, it has easy dispersion, excellent thixotropy and strong hydrophobicity, suitable for coatings, cosmetics, silicones and other fields.
Outstanding easy dispersion - Moderate specific surface area, convenient dispersion and strong dispersion stability, reducing processing difficulty
Excellent thixotropic performance - Precisely regulates system rheology, strongly resists sagging and settling, ensuring construction uniformity
Strong hydrophobic modification - Fully treated with polydimethylsiloxane, extremely strong hydrophobicity, suitable for complex polar systems
Paint film performance enhancement - Improves pigment dispersion and stability, enhances paint film adhesion, and optimizes comprehensive coating quality
Wide system compatibility - Good chemical inertness, compatible with coatings, inks, silicones and other systems, with significant flow aid effect
Coating systems - Including powder coatings and liquid coatings, anti-sagging and anti-settling, improving construction and service performance
Ink industry - Printing inks and organic toners, improving dispersibility and fluidity, optimizing printing texture
Silicone products - Silicone rubber and sealants, improving product mechanical properties and hydrophobic stability
Daily chemicals and food - Cosmetics and food industry, as functional additives to improve product stability and user experience
Adhesives and elastomers - Enhancing rheology control, improving bonding strength and product toughness, optimizing processing performance
