Silica Matting Agent with Good Matting Performance

Silica Matting Agent with Good Matting Performance

Chemical Properties

Silica matting agent should have the following characteristics:

Easy to disperse;

Good matting performance, low addition amount can produce strong matting performance;

Little interference to the transparency of the coating film;

Little influence on the mechanical properties and chemical properties of the coating film.
