Water-based paint cannot replace oil-based paint, this is only temporary.
As the name suggests, water-based paint is paint that uses 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 generally pay attention to is water-based wood paint, which is the product with the highest technical difficulty and technological content among wood paints. Water-based wood paint has the advantages of being non-toxic, environmentally friendly, odorless, with very little volatile matter, non-flammable, non-explosive, high safety, non-yellowing, and large painting area. As people's awareness of environmental protection increases, it is becoming more and more popular in the market. welcome.
Although there are many brands of water-based wood paint on the market, they can be divided into the following four categories based on their main ingredients:
The first category uses acrylic acid as the main ingredient The main features of water-based wood paint are good adhesion and will not deepen the color of the wood, but poor wear resistance and chemical resistance, soft paint film hardness, pencil rule test is HB, poor fullness, and average overall performance. Construction defects are prone to occur. Because of its low cost and low technical content, it is the main product introduced to the market by most water-based paint companies. This is also the reason why most people think that water-based paint is not good. The advantage is that it is cheap.
The second type is water-based wood paint that is mainly composed of acrylic and polyurethane. In addition to adhering to the characteristics of acrylic paint, it also has the characteristics of strong wear resistance and chemical resistance. , some companies label it as water-based polyester paint. The hardness of the paint film is good, the pencil rule test is 1H, the fullness is good, and the overall performance is close to that of oil-based paint. At present, only a few domestic companies can produce it.
The third category is polyurethane water-based paint, which has superior comprehensive performance, high fullness, paint film hardness can reach 1.5-2H, wear resistance even exceeds oil-based paint, and has obvious service life and color matching. The advantage is that it is an advanced product among water-based paints. This technology is mastered by only a few professional companies in the world. In China, only Dongguan Dingyuan Industrial Co., Ltd. took the lead in completing the localization of this core technology and holds a national invention patent. The price of its Greenbo brand water-based paint is equivalent to the second type of water-based paint.
The fourth category is some pseudo-water-based paints, which require the addition of curing agents or chemicals, such as hardeners, paint film enhancers, special diluting water, etc. Some can also be diluted with water, but The solvent content is very high, which is more harmful to the human body. Some paints are even more toxic than oil-based paints, and some companies label them as water-based polyester paints. Consumers can easily tell the difference.
