Formulation and Introduction of Waterborne Coatings (What is Waterborne Coatings)

Paint and other products are one of the essential products in the process of decoration operation. It can be divided not only according to color brand or price specification, but also according to the knowledge of formula and details. It can be seen that consumers with different needs should combine the introduction and description of products in the early stage of purchase, and analyze and understand the following when necessary, so as to screen out high-quality coating products and obtain satisfactory results.

1. What is a waterborne coating?

Waterborne coatings refer to coatings with water as solvent or dispersion medium. Waterborne coatings have the advantages of saving resources, no pollution, good protection and good corrosion resistance. However, the water content of waterborne coatings is large, and it is easy to freeze if you don't pay attention to heat preservation during transportation. And because there is water, bacteria are easy to breed, so we should pay attention to anti-corrosion and mildew prevention. Waterborne coatings are mainly used in automobile coatings, metal coatings and interior and exterior wall coatings. Waterborne coatings have been widely used in many fields.

Two. Formulation of waterborne coatings

Waterborne coatings are divided into water-dispersible coatings (latex paints), water-soluble coatings and water-dilutable coatings.

1 is a kind of waterborne wood paint with acrylic acid and polyurethane as the main components. In addition to inheriting the characteristics of acrylic paint, it also has the characteristics of wear resistance and strong chemical resistance, and some enterprises label it as waterborne polyester paint. The paint film has good hardness, pencil ruler test 1h, good fullness and comprehensive performance close to that of oily paint. At present, only a few enterprises in China can produce it.

2. It is a waterborne wood paint with polyurethane waterborne coating as the main component. Its comprehensive performance is superior, its fullness is high, and the hardness of paint film can reach? 1.5-2h？ Wear resistance even exceeds that of oily paint, and it has obvious advantages in service life and color matching. It is an advanced product in water-based paint. Only a few professional companies in the world have mastered technology. In China, only Dongguan Dingyuan Industrial Co., Ltd. took the lead in completing the localization of this core technology and has a national invention patent. Its "Lv Bo" brand waterborne paint is equivalent to the second kind of waterborne paint.

3. It is a waterborne wood paint with acrylic acid as the main component. Its main characteristics are good adhesion, which will not deepen the color of wood, but poor wear resistance and chemical resistance, and soft paint film. What are the pencil rules? hb？ , the fullness is poor, the comprehensive performance is average, and the construction is prone to defects. Because of its low cost and low technical content, it is the main product that most water-borne coatings enterprises push to the market. This is also the reason why most people think that water-based paint is not good. Its advantage is that it is cheap.

From the above description, we can know that water-based coatings are different from other materials. It has the advantages of saving resources, no pollution, good protection and good corrosion resistance, so it is not completely suitable for all fields. In addition, through the information about the formula, we can know that there are three kinds of waterborne coatings on the market: water-dispersible coatings (latex paints), water-soluble coatings and water-dilutable coatings, each with its own characteristics.
