Lithium Silicate (LS)45 (Solids 23%) is an aqueous polysilicate solution with a molar ratio of 4.5 (ranging 4.35-5.0) that has a high concentration of lithium produced with Lithium Hydroxide. The reactive silicate forms a stable, high ratio, low viscosity solution that results in lower levels of water in coatings and can dramatically improve film formation, water resistance, abrasion, hardness and bonding properties for many applications, including concrete surface treatments, specialty paints and coatings. Adhesion: Addition of Lithium Silicate to Sodium or Potassium Silicates improves the adhesion to a wide variety of substrates.
