How to introduce latex paint
Advantage 1: Health and environmental protection. Various additives such as liquid chemicals harmful to film forming, dispersion, wetting, leveling, anti-corrosion and mildew prevention added to achieve coating performance are omitted.
Advantage 2: Convenient transportation and storage. The water content of ordinary coatings is about 20-50%, but in powder coatings, the water is added only when it is used on site, that is, it needs neither transportation nor storage. In addition, when the transportation and storage temperature is lower than 0℃, water-containing coatings often freeze, while latex powder coatings do not have this problem.
Advantage 3: no preservatives are needed. In traditional liquid coatings, there are both water and bacteria in food, which is easy to be contaminated by bacteria. Therefore, in order to prevent deterioration, preservatives should be added, while latex powder coatings have no bacterial pollution problem and do not need preservatives. Latex powder coatings have so many advantages that the production process, like traditional coatings, also needs a high-speed disperser. However, various production processes and manufacturing links such as powder mixing, pigment dispersion, equipment selection, process control, finished product inspection and storage are much more complicated than traditional coatings. Therefore, for a long time, wall color powder coatings have not become popular.
