Matting Agent Silica 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.
