Matting powder is widely used in paints and coatings because it can reduce the gloss of the coating and has a matte effect. There are currently many matting powder brands on the market, and the quality of domestic brands and imported brands varies. Different brands of matting powder have different matting effects. The more well-known imported brands include Degussa from Germany, Grace from the United States, Tosoh from Japan, etc. What problems will you encounter when using matting powder? Below is a brief description.
1. What are the functions of matting powder for paint? As the name suggests, it has a matting effect and can enhance scratch and abrasion resistance, has a certain deodorizing and dehumidifying effect, is waterproof and heat-insulating, and increases the permeability of paint, etc.
2. Adding matting powder to interior wall paint can control the brightness of the interior wall paint surface. Generally speaking, there is no certain standard for the amount of matting powder added. Different manufacturers control the concentration differently, which will affect the amount of addition. The greater the amount of matting powder added, the darker the brightness. The specific proportions are added according to the different levels of paint brightness. If matting powder is used in color masterbatch, its addition amount is generally 6%. This indicator is only a reference amount. The specific amount to be added still needs to be adjusted according to the formula of the paint and the requirements of the product. In UV coatings, the addition amount of 5-8 can produce a semi-matte effect, and the amount can be continued to increase if required. Customers can adjust the formula according to their own needs.
