High Resistance Building Paint Styrene-acrylic Emulsiona pH Value 7.0 - 9.0
Product Description
The main component of styrene acrylic emulsion high-resistance architectural paint is styrene acrylic emulsion, which is a milky white liquid obtained by emulsion polymerization of styrene and acrylate monomers. The solid content is between 40 and 50%, the viscosity is between 80 and 2000 mPa·s, and the pH value is between 7 and 9. This paint has good adhesion, transparency, water resistance, oil resistance, heat resistance and aging resistance.

Advantages of Styrene Acrylic Emulsion Architectural Coatings
Application Advantage 1: Good Adhesion
Styrene acrylic emulsion has good adhesion properties, which allows the coating to be firmly fixed on the building surface, making the coating wear-resistant and durable.
Application Advantage 2: Excellent Waterproof and Breathable Properties
Styrene acrylic emulsion not only has good waterproof and moisture-proof properties, but also allows the components to maintain good breathability after painting, making it easier for the building to eliminate internal moisture.
Application Advantage 3: Good Weather Resistance
Styrene acrylic emulsion has good weather resistance, allowing it to be used in harsh weather conditions, maintaining the strength of the coating and the appearance of the appearance.
Application Advantage 4: Wide Range of Use
Styrene acrylic emulsion can be used on most building surfaces, such as cement, gypsum, wood, metal, etc., and can be used in a variety of coating methods such as internal and external wall and roof coatings.
Application Advantage 5: Can be used in conjunction with other materials

Production Technology
The production of styrene-acrylic emulsion high-durability coatings involves a multi-step process:
- Pre-emulsification: Mixing styrene, acrylic esters, emulsifiers, and water to form a stable emulsion.
- Polymerization: Initiating polymerization using initiators under controlled temperature and pressure conditions.
- Neutralization & Dilution: Adjusting the pH and diluting the polymer emulsion to the desired solids content.
- Formulation: Adding pigments, fillers, and additives to the emulsion to create the final coating formulation.
Theory
The durability and performance of styrene-acrylic emulsion coatings are attributed to the copolymerization of styrene and acrylic esters. Styrene enhances hardness, scratch resistance, and weatherability, while acrylic esters provide flexibility, adhesion, and water resistance. The resulting copolymer forms a dense, cross-linked film that resists degradation from environmental factors.
