Lithium Silicate

Lithium Silicates are preferred to sodium and potassium silicates for many applications including specialty paints and coatings, welding rod binders, refractory, ceramics and glazes. The main area of application currently, however, is concrete surface treatment. Lithium silicate chemical hardeners for concrete have been growing in market share in comparison to sodium or potassium silicates for some time now. Bearing in mind the changing needs of the industry, Sterling Chemicals has entered the Lithium Silicate manufacturing sector under its flagship “Diamond” brand.
