Lithium Silicate Concrete Densifier & Hardener
CAS Number: 10102-24-6
Lithium silicate concrete densifier is a penetrating chemical hardener that reacts with calcium hydroxide (Ca(OH)2) in the concrete to form additional insoluble calcium silicate hydrate (CSH), permanently filling and sealing the capillary pores. It dramatically increases surface hardness, abrasion resistance, and dust-proofing of concrete floors. Lithium silicate penetrates deeper than sodium or potassium silicate and produces smaller, more stable reaction products.
