So, what is colloidal silica?

Colloidal silica is a stable liquid solution of extremely fine amorphous silion dioxide powder. This solution has suspended non porous particles of silica which are as fine as 1-10 nanometers. Due to this level of fineness, there is no settling of the powder in the solution.

How is colloidal silica used in Investment Casting?

Colloidal silica acts as a binder to refractory materials like powder and aggregates use to create investment casting shells. Colloidal silica helps to create ceramic shells with high temprature stability and strength. Colloidal silica is extremely essential and potentially irreplacable in the field of investment casting.

Chosing wrong quality of colloidal silica can lead to higher number of rejection and even complete failure of the product. 

We at Vstake Overseas understand that colloidal silica carries such a critical role in the field of investment casting and therefore we take utmost care in our manufacturing facility in India.
