application instruction in coating
1. Paint matting agent pre-dispersion method:
Use 80-90% (by weight) solvent or resin to add 10% silica matting agent, mix well, use sanding or three-roller to light over one side, and then add as needed.
- Direct addition: Add the required matting agent to the resin, and disperse it at high speed.
