In developed countries in Europe and America, the penetration rate of water-based paint has reached 80% or more. However, in China, the development of water-based paint is only just on the high-speed road. Although it is still in a weak position, its share has grown rapidly. Nowadays, high hardness waterborne wood lacquer, outdoor waterborne wood lacquer, waterborne antirust lacquer, waterborne metallic paint and other new products are listed. In the near future, waterborne lacquer will eventually dominate the mainstream paint market. Water-based paints are more and more popular with the market because of their advantages of non-toxic, environmental protection, odorless, little volatile matter, high safety with no inflammability, no explosion, high brushing area, and so on. The following Xiaobian will bring you to know waterborne wood paint:

Waterborne wood paint knowledge
Waterborne wood lacquers are paints that use water as a diluent. Waterborne wood paint can generally be divided into three categories
The first type is water-based wood lacquer with acrylic acid as the main component. Its main feature is good adhesion, it will not deepen the color of wood, but its wear resistance and chemical resistance are poor. Due to its low technological content and low cost, it has become the main product on the market.
The second category is water-based wood lacquer that uses acrylic and polyurethane as the main components. In addition to the characteristics of acrylic paints, it also adds polyurethane wear resistance and chemical resistance.
The third category is a 100% polyurethane water-based wood lacquer. Its wear resistance is even several times that of oil-based lacquer. It is an advanced product in waterborne lacquer, but this technology is only available for a few specialized companies.
Although the types are clear, it is not easy to distinguish waterborne wood lacquers on the market. Because manufacturers are not unified in the name and composition of water-based wood paint, it is easy for consumers to confuse. For example, water-based wood lacquer with acrylic acid as the main ingredient has two standard methods of acrylic acid and acrylate. What is more, the water-based lacquer, which is based on a composition of acrylic and polyurethane, is marked as a water-based polyester lacquer. Consumers are best able to judge by visual inspection and nose smell: Acrylic acid is a milky white liquid with a slightly sour taste. Polyurethane is a translucent liquid like egg white, with a hint of oily aroma. Of course, the most reliable method is to purchase professional waterborne wood paint manufacturers.
Advantages and disadvantages of waterborne wood coatings
A, water-soluble paint, non-toxic environmental protection, does not contain harmful solvents such as benzene, free of free TDI.
B. The construction is simple and convenient, and it is not easy to have common problems such as bubbles, granules and other oil paints, and the paint film has a good feel.
C. The solid content is high and the paint film is full and tough.
D, no yellowing, excellent water resistance, no burning.
E, rust, high temperature.
F. Simultaneous construction with other paints such as latex paint
G. Some water-based paints have low hardness and are prone to scratches. This should be done with special care.
In general, except for slightly higher prices, water-based paint is a good choice both in terms of construction and environmental protection.
With the increase in people's awareness of environmental protection, waterborne paints with little volatile matter are welcomed by the market. Industry sources said that the development of water-based paint will be the general trend, and will fully replace the oil paint. For example, the interior and exterior paints, metal paints, etc. that we use have corresponding water-based paint products. This is exactly the same as the definition of Europe and the United States. The oil paint uses organic solvents.
