Warning: High pH can lead to ASR (Alkali-Silica Reaction) and cracking.
Lithium is the smallest stable alkali metal on earth. In Lithium Silicate, a single Silicon Dioxide ($SiO_2$) molecule is attached to a Lithium atom. This creates a high-ratio solution with a much higher density of silicate bonds compared to larger molecules.
The Penetration Advantage:
Because the molecular size is significantly smaller than Sodium or Potassium Silicates, CETEX Lithium Silicate penetrates several millimeters deep into the concrete matrix.
It reacts with Calcium Hydroxide to form Calcium Silicate Hydrate (C-S-H), which settles into the pores to seal, strengthen, and densify the surface from within.
While Lithium Silicate is a premium specialty chemical, it offers superior technical and economic advantages:
Xetex Industries Private Limited (India) manufactures a wide range of high-purity silicates. Our Lithium Silicate is supplied as a highly concentrated liquid, designed to be diluted 2-3 times with water at the site.
