Waterborne coating classification
Although there are many brands of waterborne wood lacquers on the market today, the main components of the market are divided into the following three categories: The first type is water-based wood lacquer with acrylic as the main component. The main feature is good adhesion and does not deepen the color of the wood, but the abrasion resistance and chemical resistance are poor. The hardness of the paint film is soft. The pencil rule is HB. The fullness is poor, the overall performance is general, and the construction is prone to defects. Because of its low cost and low technical content, it is the main product that most water-based paint companies are bringing to the market. This is why most people think that water-based paint is not good. The advantage is that it is cheap. The second type is a water-based wood lacquer based on the combination of acrylic acid and polyurethane. Its characteristics are not only adhering to the characteristics of acrylic lacquer, but also increasing the wear resistance and chemical resistance. Some enterprises are marked as water-based polyester paint. . The hardness of the paint film is good, the pencil rule is 1H, the fullness is good, and the comprehensive performance is close to the oil paint. At present, only a few companies in China can produce. The third type is polyurethane water-based paint, which has superior comprehensive performance, high fullness, hardness of paint film can reach 1.5-2H, wear resistance even exceeds oil paint, and has obvious advantages in service life and color matching. Advanced products, the technology is only available in a few professional companies around the world. In China, only Dongguan Dingyuan Industrial Co., Ltd. has taken the lead in completing the localization of this core technology and has a national invention patent. Its “Green Bo†brand water-based paint price is equivalent to the second type of water-based paint. Although the type is clear, it is not easy to distinguish the water-based wood lacquer on the market. Because manufacturers do not harmonize the name and composition of water-based paints, it is easy for consumers to be confused. For example, the water-based paint containing acrylic acid as the main component has two specifications of acrylic acid and polyurethane. Consumers are better able to use the nose to help judge: acrylic is a bit sour, polyurethane is a little oily fragrance. Of course, the most reliable way is to buy products made by professional waterborne wood lacquer manufacturers.
