Product Name: Colloidal Silica for Paints and Coatings Model NO.: JN-30 Color: Clear Composition: Organic Material Promoter Composition: Stabilizer Characteristic: Waterproof Main Agent Composition: Inorganic Adhesive Material Classification: Thermosetting Material: Silicone Application: Construction Morphology: Water-Soluble Bonding Function: Instant Adhesive Formula: Msio2.Nh2o CAS No.: 7631-86-9 Trademark: Yinfeng Transport Package: Plastic Drums Specification: SiO2 content Origin: China HS Code: 35069900 Product Description Silica sol belongs to colloid. It is odorless, tasteless and nontoxic. Its chemical molecular formular is mSiO2.nH2O.1.Since the colloid grains are minute (10-20nm) and have relatively large specific surface area, the grains themselves are colorless and transparent, so they do not affect the natural color of the materials to be covered.2.With low viscosity, it can soak the places where water soaks, therefore, it presents excellent dispersion and permeability when being mixed with other substances.3.When the moisture contained in silica sol are evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.The specification of JN-30 is as follows:ItemSiO2%Na2O%PHDensity(g/cm3)Viscosity(mPa.s)Particle size(nm)AppearenceStorge lifeJN-3029-310.28-0.59-111.19-1.21≤78-15Slight blue and transparency12 monthsUsed in coating industry.It makes the paints firm.It also possesses features,such as anti-contamination,dustproof,anti-aging,fireproof, etc.
