Application

1.It is suitable for styrene and alcohol solvent, especially for polymer resins such as unsaturated polyesters, epoxies and vinyl esters.

2.To replace fumed silica

3. Cosmetic

4. Plastic

Using

It can be added directly in powder under any point of producing procedure

It's addition level is typically 30-50% less than Fumed Silica use levels.

Adding level is commonly 0.2%~2.0%.
