Application

Powdery instant potassium silicate is widely used in refractory binders, oilfield drilling fluid additives and other fields with special applications.

Important Notice

We normally list 24 months as the shelf life in our COA, the real shelf life is actually much longer than 24 months if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
