Noble silicates are used in a numerous grades of paint and surface coating applications. These are used as binders to produce mineral type silicate paints.
Due to its properties these paints provide excellent decorative and protective coating for buildings & metal surfaces. Potassium Silicate is preferred over sodium silicate as it does not form carbonates on exposure to atmosphere and remain free from frosty bloom (white carbonate deposits).
Potassium silicates are used for zinc rich anti-corrosion coatings, which when cured are completely water resistant.
Sodium Silicates are used to coat TiO2 pigments so that the whiteness does not fade under the influence of environmental conditions.
Advantages of silicate paints
- Excellent water vapour permeability
- Good adhesion
- Low absorbability
- Operational lifetime is Long & Durable
- Appearance remain constant & natural.
- Highly stable & persistent towards acids.
