Potassium Silicate

About Potassium Silicate

SPECIFICATION Colour Clear to Whitish Viscous Liquid Odour Odourless or slight musty odour K2O 8.30 -12.70 % w/w SiO2 20.8 - 26.50 % w/w Solids 29.0 - 39.20 % w/w Weight Ratio 2.10 - 2.50 Molar Ratio 3.29 - 3.92 pH 11.3 - 11.70 Specific Gravity 1.25 - 1.38 at 25C FEATURES, BENEFITS & APPLICATIONS Potassium Silicate is more soluble and compatible with other ingredients than Sodium Silicate. It is used in various formulations like heavy duty detergents,soaps, etc. Compared to Sodium Silicate it does not form white carbonate film i.e. efflorescence on exposure to atmosphere. This makes them preferred choice in decorative coating, paints, etc. It is used as binder during production of welding rod, as soft violet flame of Potassium is easier to see through during welding compared to blinding yellow flame of Sodium. Potassium Silicate isconvenient source of Potassium for plant nutrients. As it melts and flows at high temperature, it is used as binder in refractory mortar and specialty cements. Non tacky property makes it important additive in mortars, acid lining, etc.
