Performance and Usage:

Nature：

Higher hydrophobicity, thickening and thixotropic effect, transparency, and reinforcement

Thickening, thixotropic and reinforcing agents for room temperature vulcanized (RTV) silicone rubber, whose hydrophobic properties give greenhouse vulcanized silicone good shelf life

Rheological control of adhesives

Anti settling, anti sagging, and thixotropic control of coatings and inks

Improve the free flowability of powder coatings and prevent clumping

 

Application：

Room temperature vulcanized (RTV) silicone rubber, especially electronic potting adhesive

Coatings and inks

Adhesives and sealants

powder coating
