Sílica Coloidal

Levasil is an alkaline colloidal aqueous solution of amorphous silica with about 40% solids by weight. It is used in foundry applications as a binder and in adhesives to improve thermal stability and mechanical strength.

• The description claims that Levasil can withstand temperatures up to 1200°C with minimal shrinkage and good thermal shock resistance.
• The description claims that Levasil helps direct and optimize adhesive viscosity and reduce drying time.
