SiO2 Powder for Adhesive
Precipitated silica is widely used in adhesive and sealant industry.
First,silica is an effective reinforcing filler, which can significantly improve the bonding strength of adhesives and sealants.
In addition,in the field of sealants and adhesives, silica can be used as a thickener and thixotropic agent. It can increase viscosity, ensure free flow, and prevent caking, hanging and collapse during curing.
