Waterborne coating refers to the coating with water as solvent or dispersion medium. The water-based coating has the advantages of saving resources, no pollution, good protection and corrosion resistance. But the water content of the water-based coating is large, if the heat preservation is not paid attention to in the transportation process, it is easy to freeze. And also because of water, easy to breed bacteria, so pay attention to anti-corrosion and mildew. Water based coating is mainly used for automobile coating, metal coating and interior and exterior wall coating. Waterborne coatings have been widely used in many fields.

一、 what is water-based coating

As the name implies, water-based coating is a kind of coating with water as solvent or dispersion medium. Water-based coating can be divided into three categories: water-soluble coating, water dilution coating and water dispersion coating, which is often called latex coating.

Water based coatings are widely used in the industry. All the interior and exterior wall coatings, water-based metallic coatings, water-based fluorocarbon coatings, water-borne water-based multi-color paints, automobile paints, etc. have corresponding water-based paint products. Waterborne wood paint is the product with the highest technical difficulty and technological content in wood paint.

二、Characteristics of Waterborne Coatings

Due to the advantages of water-based coatings, such as environmental protection, constant yellow, easy construction, many small and medium-sized enterprises have also seized the market of water-based coatings, but the quality is uneven. Understanding the characteristics of water-based coatings is an important prerequisite for us to buy water-based coatings.

A. advantages of water-based coating

★ the water-based coating uses water as the dispersing medium and only uses a small amount of low toxic alcohol ether organic solvent, which is safe, environmentally friendly and resource-saving, eliminates the risk of fire during construction, and is conducive to reducing air pollution.

★ the water-based coating has very good adaptability to the material surface. It can also be applied in wet environment, with strong adhesion.

★ water based paint containers and tools can be cleaned with water, and unused paint can be stored in a cool place, which saves paint resources and reduces the consumption of cleaning solvents.

★ the electrophoretic coating of water-based coating is uniform and well leveled. The small gap and corner can be coated with a certain thickness of coating, which is convenient for construction and has good protective performance.
