Hardener

Lithium Silicate 

Harden X SI provides superior protection against salt intrusion as it hardens, seals, and densifies concrete and masonry surfaces. The lithium silicate formulation of Harden X SI reacts with the calcium hydroxide in the concrete to form stable, insoluble tri-calcium silica structures and chloride screens for maximum resistance to dusting, abrasion, bacteria, and chemical attack.

Advantages of Lithium Technology

Chemical reactions of lithium silicates are more stable than those caused by the volatile conventional silicates, allowing the material to penetrate more deeply and react more evenly throughout the concrete. Other silicates absorb moisture and cause ASR, raising the PH of the surface and weakening the substrate over time. Lithium silicates are PH neutral and insoluble, providing maximum water resistance. The cutting edge technology in our proprietary lithium formulation makes Harden X SI the most advanced product of its kind.
