This kind of silica sol is used for binder of fireproof materials,coating industry,paper making industry and so on.
Characteristics
1 colloidal Silica belongs to ordinary chemicals.
2 It is odorless, tasteless and non-toxic.
3 Its chemical molecular formula is mSiO2.nH2O.
4 With low viscosity, it can soak the places where water soaks, therefore, it shows excellent dispersion and permeability when mixed with other substances.
Usage
Used as various fire-proof material. It has high bonding strength and high heat-resisting performance (1500-1600), etc.
Used in coating,painting industry, it makes the paints more firm. It also possesses features, such as dust-proof, anti-aging, fire-proof, etc. Used in precision casting of thin, it covers to increase the cover strength, improves the casting smooth finish. It can be used to replace ethyl silicate for molding so as to reduce the cost and help improve the operating conditions. Having large specific surface area, colloidal silica can be used as catalyst ,binder and catalyst carrier. Used in paper-making industry,Email:anna.zhao@88better.cn
