Fumed Silica is the amorphous, pyrogenic form of silica produced by burning silicon compounds in high-temperature flames. The product is a fine, white powder with a large surface area and the ability to form three-dimensional network.
Hydrophobic Fumed Silica is known as a type of fumed silica. They differ from Hydrophilic Fumed Silica by having waterproof and being insoluble in water due to chemical treatment with DDS (Dimethyldichlorosilane)
1.Characteristics of Hydrophobic Fumed Silica - Very small particle size ~ 4,5 μm - Contact surface area: 110 ~ 320 +/- 20 (m2/g)
2.Properties - Ability to control rheology and viscosity of the product - Good reinforcement capability for construction materials - Improved free flows properties - Anti-sagging and anti-settling for paints and water-based inks. - Hydrophobic properties - Anti-caking properties
3.Scope of applications Due to waterproof characteristics of Hydrophobic Fumed Silica, they are commonly applied in the production of: - Paint: Enhance water resistance for waterproof paints, epoxy paints, etc. - Ink: Help control free flow properties of water-based ink products. - Cosmetics: foundation cream, face powder, sunscreen, lipsticks, etc. - Construction: Help improve reinforcement capabilities, anti-sagging properties, and water resistance in cement products and waterproofing materials.
