What is Water-based acrylic Emulsion? How is water-based acrylic emulsion classified?

Water-based acrylic emulsion is a type of emulsion that is produced by emulsion polymerization, in which various monomers of acrylic acid are polymerized. This emulsion is widely used in the coatings, adhesives, paper, and textile industries. The production process can be simply described as follows: First, mix part of the acrylic acid monomers, then add them to water that has been dissolved with an emulsifier and stirred at high speed to form an emulsion. Then, add the initiator and heat the mixture to a certain temperature for polymerization reaction. Gradually add the remaining monomers for polymerization, and finally add the chain transfer agent to terminate the reaction to produce acrylic emulsion. Water-based acrylic emulsion has high gloss, fast drying, water resistance, oil resistance, and heat resistance properties. These properties make it excel in various application scenarios.

In addition, ‌ water based acrylic emulsion also has good weather resistance and alkali resistance, ‌ has good adhesion to the surface of masonry, ‌ wood and steel. ‌ it can be prepared flat, ‌ semi-gloss and high gloss latex paint, ‌ and high quality flooring, ‌ cement tile and tennis court finish coatings, ‌ showing its versatility and high performance characteristics. ‌

The production and application of water-based acrylic emulsion reflects the importance of environmental protection and sustainability ‌ because it reduces the environmental pollution problems caused by traditional solvent-based coatings. ‌ With the improvement of environmental protection awareness, ‌ water-based coating has become the main direction of the development of coating industry, ‌ and water-based acrylic emulsion as a kind of pollution-free coating, ‌ its development and application prospects are broad

Water-based acrylic emulsion classification

Classified by product composition

Water-based acrylic emulsion is classified by emulsion type, including pure acrylic emulsion, ‌ silicone acrylic emulsion, ‌ styrene acrylic emulsion, ‌ vinegar acrylic emulsion and so on.

Pure acrylic emulsion: This is a basic acrylic emulsion, ‌ on the basis of which a variety of coatings can be formulated.

Silicon-acrylic emulsions: This emulsions combines the properties of siloxane, ‌ is commonly used in applications that require increased weather and chemical resistance.

Styrene acrylic emulsion: An emulsion formed by copolymerization of styrene with acrylic acid, ‌ often used in paints requiring high gloss and rapid drying. ‌

Acrylic emulsion: Emulsion formed by copolymerization of vinyl ‌ acetate with acrylic acid, ‌ suitable for applications requiring specific viscosity and chemical resistance. ‌

These classifications reflect the diversity of acrylic emulsions in composition and use, ‌ the appropriate emulsion type can be selected according to the specific application needs

Classified by performance and application requirements

Pure acrylic emulsion wood coating: This kind of coating has low cost, good hardness, good wear resistance, high transparency, and good chemical resistance, but the construction conditions are high, and the film formation is slightly poor during low temperature construction.

Acrylic microshea coating: This coating has low surface tension, good wettability, permeability and leveling for wood, and can make the paint film uniform and good quality. It also has good flexibility and impact resistance, high gloss, hardness, wear resistance.

Self-crosslinked acrylic emulsion wood coating: This coating is a single-component coating, characterized by fast drying film, good transparency, high hardness, convenient construction and high efficiency, can be constructed at room temperature or low temperature, with good viscosity resistance and film flexibility.

Modified water-based acrylic emulsion: including epoxy modification, polyurethane modification, silicone modification, organic fluorine modification and self-crosslinked water-based acrylic emulsion. These modified emulsions offer different performance optimizations according to specific needs, such as weather resistance, chemical resistance, etc.

These classifications are divided according to different performance and application requirements to meet the needs of a variety of industrial and home applications‌.
