CHARACTERISTIC

HJSIL provides thickening and thixotropic effects in paints, acrylics and coatings. It also provides performace benefits for polyurethanes, polyesters and epoxies.

Reinforcement
HJSIL 200 as a filler improves the mechanical and compatibility properties of silicone sealants and silicone glues.

Anti-settling
HJSIL improves the suspension behavior in liquid systems, such as pigmented coatings or resins containing fillers.

Anti-caking
HJSIL 200 can improve flow characteristics. It can be used to improve the storage stability of powders that are especially prone to caking. HJSIL can also be used to improve flow characteristics and prevent flow problems.
