Applications

Adhesives and Sealants

INNOSIL 150 fumed silica is widely used in all kinds of adhesive and sealants industries, e.g. silicone sealants, PVC-plastisol sealant, polyacrylate sealant, expoxy adhesive, polyurethane adhesive, unsaturated polyester, polyurethane water-based adhesive, etc.


It is mainly used as additives for anti-sag, rheology control and anti-settling; also  used as rheology control and reinforcing agents in sealants, and improves the storage stability and processability of adhesives and sealants.


RTV Silicone Sealant, HTV Silicone Rubber

INNOSIL 150 in RTV silicone sealant


INNOSIL 150  provides thixotropy and reinforcement for RTV silicone sealants, while its shear-thinning property provides thickening and sag resistance at rest or low shear and thinning at high shear for easy application.


Applications

• RTV Silicone Sealant
• HTV Silicone Rubber

• Vacuum Insulation Panel

Functions:

• Provide the good Reinforcement and thixotropy for RTV Silicone Sealant 

• Improve the reinforcement for HTV Silicone Rubber
• Heat and sound insulation
