Powder coating is a completely different form from general coatings, it exists in the state of fine powder. Because no solvent is used, it is called powder coating. The main characteristics of powder coatings are: harmless, high efficiency, saving and environmental protection. Its advantages are as follows: 1. Health and environmental protection. All kinds of liquid chemical harmful film-forming, dispersing, wetting, leveling, anti-corrosion and mildew-proof additives added to achieve coating performance are omitted. 2. Convenient transportation and storage. Ordinary coatings contain about 20-50% of water or solvents, while powder coatings have neither water nor solvent, and are completely solid, which is convenient and safe to transport. In addition, coatings containing water or solvents, when When the temperature of transportation and storage is lower than 0 ℃, it tends to freeze, and powder coatings do not have this problem. 3. No need for preservatives In traditional liquid coatings, there are both water and bacteria food, which are easily contaminated by bacteria. Therefore, in order to prevent deterioration, it is necessary to add preservatives, and latex powder coatings have no bacterial contamination problem and do not need preservatives. 4. Compared with the odor residues of ordinary traditional coatings, this paint can dissipate quickly, and can It is said to be applied and wiped away.
