How Much Do You Know About Types of Water-Based Coatings?

Water-based coatings can be categorized based on the following aspects: ① Binder type; ② Drying method; ③ Application field.

A relatively clear method involves considering the stable states of different binders in water, categorizing them into true solutions, colloidal solutions, dispersions, and emulsions.

Generally, water-based coatings are classified into three types based on the relationship between their binders and the aqueous phase: solution coatings, colloidal solution coatings, and emulsion coatings.

The binders in water-based coatings fall into two categories: those with highly polar structures that enable dissolution or swelling in water, and those that become water-soluble through chemical reactions forming salt derivatives. Water-soluble binders are generally classified as nonionic, anionic, cationic, and others.

Common monomers include: acrylic esters, methacrylic esters, styrene, vinyl acetate, ethylene, butadiene, vinyl chloride, and other vinyl esters.

Commonly used emulsion resins include: alkyd resin emulsions, epoxy resin emulsions, silicone resin emulsions, and asphalt emulsions.

That concludes our overview of water-based coating types for today. As we all know, China's coatings industry has grown from humble beginnings to become the world's largest producer and consumer of coatings. This remarkable journey owes much to the tireless efforts of every coatings enterprise. Enze Chemical will be guided by the vision of “accelerating the cultivation of globally competitive first-class enterprises,” adhering to the strategic framework of “smart manufacturing, global market expansion, and value maximization.” Through concrete actions, we will carry forward and practice this commitment, dedicating ourselves wholeheartedly to the nation's anti-corrosion industry while opening a new chapter for Enze Chemical.
