The Role Of Matte PU Paint Plus Matte Wax Powder

Customer consultation: Adding too much matting powder to matte PU will cause flocculent matting and cotton-like appearance. I hope that matting wax can solve this problem. The role of adding matting wax powder to matte PU paint is mainly reflected in the following aspects:

1. Matting effect

Matt wax powder is a common matting powder component, which can achieve the matting effect by controlling the size and shape of the particles. Adding an appropriate amount of matting wax powder to matte PU paint can make its surface present a soft matte effect, thereby eliminating reflection and gloss, making the coating surface softer and more natural.

2. Improve anti-pollution and adhesion

Matt wax powder can not only reduce gloss, but also improve the anti-pollution and adhesion of the coating surface. This is because the matting wax powder forms a film-like structure in the coating, which can increase the roughness of the coating surface, thereby improving its resistance to pollutants. At the same time, matting wax powder can also enhance the adhesion between the coating and the substrate, making the coating more firm and durable.

3. Enhanced scratch resistance

Matt wax powder also has the function of enhancing the scratch resistance of the coating. After adding matt wax powder to the coating, a protective film can be formed, which can resist scratches and wear from external objects, thereby extending the service life of the coating.

4. No impact on recoating adhesion

Adding an appropriate amount of matt wax powder will not affect the recoating adhesion of matt PU paint. This means that after the coating is dry, it can be easily re-coated without causing a decrease in adhesion between the coatings.

5. Transparency and dispersibility

Some specific matt wax powders (such as W-11) can provide better transparency and excellent dispersibility when added to the paint system. This is especially important for application scenarios where the transparency of the coating needs to be maintained.

In summary, the addition of matt wax powder to matt PU paint can significantly improve the performance of the coating, including matt effect, anti-pollution, adhesion, scratch resistance and transparency. However, the amount of matt wax powder added needs to be adjusted according to the specific situation to ensure the best coating effect.
