What are the Differences Between Silicone-acrylic, Pure Acrylic and Styrene-acrylic Emulsions？

Silicone-acrylic emulsion is formed by polymerizing organosilicon monomers containing unsaturated bonds with acrylic monomers. The aim is to combine the high-temperature resistance, weather resistance, chemical resistance, hydrophobicity, low surface energy and non-polluting properties of silicone with the high color retention, flexibility and adhesion of acrylic resins to prepare environmentally friendly emulsions and coatings for buildings that are highly weather-resistant, water-resistant and anti-polluting. Silicone-acrylic is generally used in high-end silicone-acrylic exterior Latex Paint and real stone paint due to its good weather resistance and stain resistance, but its relatively high price.

Advantages of silicone-acrylic emulsion:

• Silicone-acrylic emulsion has good water resistance, acid resistance, weather resistance, alkali resistance and stain resistance.
• Silicone-acrylic emulsion is composed of pure acrylic and silicon. The coating film does not turn yellow, is resistant to ultraviolet rays and aging.
• The film of silicone-acrylic emulsion is dense, tough, has high hardness and excellent resistance to water whitening.
• Silicone-acrylic emulsion has high gloss and good color rendering of real stone paint.

Pure acrylic emulsion is a resin that is completely polymerized from acrylic monomers. Pure acrylic is generally used more for exterior walls due to its good weather resistance and moderate price.

Advantages of pure acrylic emulsion:

• Non-toxic, non-corrosive, non-flammable, it is a water-based substance and not a dangerous good.
• Fine particle size, high gloss, excellent weather resistance, excellent anti-sticking property, and wide applicability.

Styrene-acrylic emulsion is formed by the polymerization of styrene-based monomers and acrylic-based monomers. Styrene-acrylic is more commonly used for interior walls due to its average weather resistance and low price.

Advantages of styrene-acrylic emulsion:

• The polymerization rate is fast, and the molecular weight of the product is high. The polymerization can be carried out at a relatively low temperature.
• The viscosity of styrene-acrylic emulsion polymerization is low, which is conducive to stirring, heat transfer, transportation and continuous production. Water is used as the medium, which is inexpensive and safe.
• It is conducive to the direct application of styrene-acrylic emulsion polymerization and the production of environmentally friendly products, such as water-based paint, adhesives, paper, leather, fabric treatment agents, etc.

The utilization rate of styrene-acrylic emulsion is more stable and effective than the other products.
