Acrylic emulsions can be used in a wide variety of industries and applications. Some common types of acrylic emulsions include:
Pure acrylic emulsion: It&#;s 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: It&#;s a synthetic emulsion of acrylic and styrene.
Vinyl acetate-ethylene (VAE) emulsion: It&#;s a synthetic emulsion of the monomers vinyl acetate (VA) and ethylene.
Vinyl acrylic copolymer emulsion: It&#;s a synthetic emulsion of acrylic acid and vinyl acetate.
Acrylic epoxy emulsion: It&#;s an emulsion that combines an acrylic polymer with an epoxy resin.
Acrylic-polyurethane emulsions/Polyurethane dispersions (PUD): It&#;s an emulsion that combines an acrylic polymer with a polyurethane resin.
Acrylic-silicone copolymer emulsion: It&#;s 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: It&#;s 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.
Vinyl acetate-ethylene (VAE) emulsion: It&#;s mainly used for preparing adhesives, waterproof coatings, mortars, etc.
Vinegar acrylic copolymer emulsion: It&#;s mainly used as an Interior Flat Coating Emulsion.
Acrylic epoxy emulsion: It&#;s mainly used in industrial coatings, protective topcoats and floor coatings.
Acrylic-polyurethane emulsions/Polyurethane dispersions (PUD): Typically, it&#;s used for preparing high-performance coatings, sealers, topcoats, floor coatings, etc.
Acrylic-silicone copolymer emulsion: It&#;s 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.

Acrylic emulsion serves as a valuable additive in the field of construction, offering the ability to modify cement and concrete. By incorporating acrylic emulsion into these materials, one can significantly improve the adhesion between new and old concrete surfaces. This enhancement contributes to the longevity and structural integrity of structures, especially when dealing with repairs and renovations.
One of the notable applications of acrylic emulsion is in road and bridge repairs. The material's adhesive properties facilitate the bonding of new concrete to existing structures, ensuring a seamless and durable connection. This is particularly crucial in maintaining the safety and functionality of transportation infrastructure.
In the realm of construction and restoration, acrylic emulsion proves beneficial in revitalizing old buildings. When applied to aging structures, it enhances the cohesion between the original construction material and any new additions or repairs. This not only strengthens the building but also preserves its historical and architectural value.
Acrylic emulsion contributes to the increased carbonation corrosion resistance of concrete. Carbonation corrosion is a common issue in concrete structures, leading to the deterioration of steel reinforcements. By incorporating acrylic emulsion, the concrete becomes more resistant to this form of corrosion, prolonging the lifespan of the structure.
Beyond concrete applications, acrylic emulsion also finds utility in modifying asphalt pavement. The material enhances the high-temperature resistance and cold resistance of modified asphalt pavement. This improvement is particularly significant in regions with extreme weather conditions, ensuring the durability and stability of road surfaces.
In conclusion, acrylic emulsion emerges as a valuable asset in the construction industry, offering diverse benefits in the modification of cement, concrete, and asphalt. From improving adhesion between different concrete surfaces to increasing resistance against carbonation corrosion, acrylic emulsion plays a crucial role in enhancing the performance and longevity of various infrastructure elements.
