Silica Matting Agent with Good Matting in ink and paint
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.
