Waterborne paint knowledge analysis

What is water-based paint? As the name suggests, water-based paints are paints with water as the medium. For example, all our interior and exterior wall paints, metal paints, automotive paints, etc. have corresponding water-based paint products. It can be seen that water-based paint has been widely used in many industries. What we are generally concerned about is waterborne wood paint, which is the most technically difficult and high-tech product in wood paint. Water-based wood varnishes are more and more market-conscious due to their non-toxic and environmental protection, no odor, very little volatile matter, high safety, non-flammable, non-yellowing, and large painting area. Welcome. Due to the consensus on the development of the world paint market, various oil paint manufacturers have launched water-based paint products, and many foreign brands have also seized the Chinese market. The water-based wooden lacquers on the market were all over the world for a while. How to know, understand, and purchase has become a top priority for consumers. Although there are many brands of water-based wood lacquers on the market, their main ingredients are divided into the following four categories:

The first type is water-based wood lacquer with acrylic as the main component. The main feature is good adhesion, which will not deepen the color of the wood, but it is poor in wear resistance and chemical resistance, and the hardness of the paint film is soft. The fullness is poor, the general performance is general, and the construction is prone to defects. Because of its low cost and low technical content, it is the main product for most waterborne paint companies to market. This is why most people think that water-based paints are not good. The advantage is that it is cheap.

The second type is based on the composition of acrylic hometown and polyurethane as the main component of waterborne wood lacquers. In addition to adhering to the characteristics of acrylic paints, it also adds the characteristics of wear resistance and strong chemical resistance. Fat paint. The film hardness is good. The pencil rule test is 1H. The fullness is good. The comprehensive performance is close to the oily paint. At present, only a few domestic companies can produce.

The third type is polyurethane water-based paint, which has superior comprehensive performance and high fullness. The hardness of the paint film can reach 1.5-2H. The abrasion resistance even exceeds that of oil-based paint. It has obvious advantages in terms of service life and color matching. Advanced products.

The fourth category is some pseudo water-based paints. When used, curing agents or chemicals must be added, such as "hardener", "paint film enhancer", "special dilution water", etc. Some can also be diluted with water, but the solvent The content is very high, which is more harmful to the human body, and some even exceed the toxicity of oil-based paints, and some companies label them as water-based polyester paints. Consumers can easily tell the difference. Knowing the classification of water-based wood paint, consumers can choose according to their needs. If the price is cheap, just choose the first type of water-based paint; if the decoration is more than mid-range and more elegant, it is best to use the first Type II or Type III water-based paint.虽然 Although the types are clear, it is not easy to distinguish water-based wood lacquers on the market. As the names and ingredients of water-based paints are not uniform among manufacturers, it is easy to confuse consumers. For example, water-based paints with acrylic as the main component have two standard methods: acrylic and acrylic. Consumers are best able to use nasal sniffing methods to help judge: acrylic has a bit sour taste, and polyurethane has a light scent of oil. Of course, the most reliable way is to buy products made by professional waterborne wood paint manufacturers.
