Water - based coating formulation design system - matting agent
Matting agents are additives used to control the gloss of waterborne wood coatings to meet the broad needs of mainstream matt paints in today's market.The extinction mechanism of the matting agent can be arranged in an orderly manner on the surface of the coating film, so that the surface of the coating film is uneven, causing the light on the surface of the coating film to diffusely reflect, thereby achieving the purpose of extinction.

The solid content of the resin used in the waterborne wood coating is relatively low, and the effective component of the waterborne wood coating is not high. In addition, it is a dispersion system, so the matting of the waterborne wood coating is relatively easy, but the matting of different waterborne resin systems is difficult. Generally, the acrylic emulsion is relatively well-extruded than the aqueous polyurethane dispersion, but is better than the aqueous polyurethane dispersion in terms of anti-settling properties.Therefore, the selection of matting powder must be considered in different systems and uses.The matting agent can select the refractive index similar to the refractive index of the water-based resin to reduce the transparency of the coating film, and also consider its matting effect, dispersibility, anti-sinking property and hand feeling in the system.
