FUMED SILICA (ADDITIVE) FOR PAINTS & COATINGS

FUMED SILICA ADDITIVE FOR PAINTS & COATINGS:

Fumed silica is added to painting and coatings for rheological control. It can effectively prevent sedimentation and delamination of pigments, improve the weather ability and scratch resistance of coatings, and improve the bonding strength between coatings and substrates.

In-wall coatings of fumed silica help to prevent the paint from flowing down and to improve the smoothness of the wall surface. What’s more, it can greatly improve the scratch resistance and aging time of the exterior wall coating, and also the bonding strength between the coating film and the wall, the hardness of the coating film and the surface self-cleaning ability.

When fumed silica is adsorbed by powder coatings, a movable layer is formed on its surface. It improves the flowing property by preventing powder coatings from absorbing moisture and agglomerating.
The main function of fumed silica in floor paint is to improve its ability of weather resistance, scratch resistance and leveling performance.
