Common Types and Definitions of Acrylic Emulsions
Acrylic emulsions can be used in a wide variety of industries and applications. Some common types of acrylic emulsions include:
Pure acrylic emulsion: Its an emulsion copolymerized with monomers such as acrylic acid, methyl acrylate, butyl methacrylate and functional additives. The emulsion consists of pure acrylic polymer.
Styrene acrylic copolymer emulsion: Its a synthetic emulsion of acrylic and styrene.
Vinyl acetate-ethylene (VAE) emulsion: Its a synthetic emulsion of the monomers vinyl acetate (VA) and ethylene.
Vinyl acrylic copolymer emulsion: Its a synthetic emulsion of acrylic acid and vinyl acetate.
Acrylic epoxy emulsion: Its an emulsion that combines an acrylic polymer with an epoxy resin.
Acrylic-polyurethane emulsions/Polyurethane dispersions (PUD): Its an emulsion that combines an acrylic polymer with a polyurethane resin.
Acrylic-silicone copolymer emulsion: Its a synthetic emulsion of acrylic and silicone.
Application of Each Type of Acrylic Emulsion
Pure acrylic emulsion: It is a high grade waterborne emulsion, which is mainly used for preparing acrylic emulsion paint on walls, medium and high grade latex coatings for exterior walls. Not only that but it can also be used in the preparation of multi-color paints, primers, varnishes, etc.
Styrene acrylic copolymer emulsion: Its mainly used for preparing interior wall latex coating, primer, exterior wall medium and low-grade coating, but also can be prepared for adhesives, waterproofing and mortar, etc.

Additional resources:Vinyl acetate-ethylene (VAE) emulsion: Its mainly used for preparing adhesives, waterproof coatings, mortars, etc.
Vinegar acrylic copolymer emulsion: Its mainly used as an Interior Flat Coating Emulsion.
Acrylic epoxy emulsion: Its mainly used in industrial coatings, protective topcoats and floor coatings.
Acrylic-polyurethane emulsions/Polyurethane dispersions (PUD): Typically, its used for preparing high-performance coatings, sealers, topcoats, floor coatings, etc.
Acrylic-silicone copolymer emulsion: Its mainly used for preparing exterior wall coating, overcoat paint, waterproof treatment, etc.
Pros and Cons of Each Type of Acrylic Emulsion
The emulsion is a film-forming substance. Formulation content: about 10~50%, high gloss coatings can reach about 70~80%. Emulsion plays a key role in the hardness, flexibility, abrasion resistance, water resistance, weathering resistance, etc of the coating film.
Pure acrylic emulsions are valued for their versatility and wide range of applications. It has the characteristics of high gloss, excellent adhesion and flexibility, good film formation, good weather resistance, good light and color retention. At the same time, it will be relatively weak in water resistance, alkali resistance, and adhesion.
Styrene-acrylic copolymer emulsion combines the properties of styrene and acrylic. It has the advantages of strong powder coating, good scrub resistance, good water and alkali resistance, and strong adhesion. Compared with other emulsions, styrene-acrylic copolymer emulsion has relatively poor yellowing resistance.
VAE emulsions have good adhesion, flexibility and water resistance, but can take a relatively long time to form a film.
Vinegar-acrylic emulsion has good stability, good fullness and good hand feel. At the same time, water resistance, alkali resistance, and yellowing resistance are relatively poor.
The combination of acrylics and polyurethanes in a PUD provides a balance of the two materials. It offers durability, chemical resistance, UV resistance, good adhesion and flexibility, but it can be costly and construction can be relatively complex.
Acrylic-silicone emulsions combine the high temperature resistance, weather resistance, chemical resistance, water and stain resistance of silicones with the high color retention, flexibility and adhesion of acrylic resins. The film-forming property is a little bit poorer and the cost price is relatively high.
