Wacker H17 [Product Introduction]

The synthesized hydrophobic amorphous silica is produced by flame hydrolysis.

[Product Features]

It can be used as a thickener and thixotropic agent in composite materials, coatings, adhesives, and sealants, especially in vinyl esters, epoxy resins, and polyurethane systems.

Not suitable for use in pharmaceuticals, food, and feed.

Good dispersibility is a necessary condition for ensuring optimal performance.
