High Water Resistance Building Coatings Styrene-acrylic Emulsiona

Product Description

Styrene acrylic emulsion, also known as styrene-acrylate emulsion, is a copolymer emulsion obtained by emulsion copolymerization of styrene and acrylate monomers. It appears as a milky white liquid, sometimes with a blue light, with a solid content usually between 40% and 50%, a viscosity range of 80 to 2000mPa·s, and a pH value between 8 and 9. Styrene acrylic emulsion has good adhesion, transparency, and water resistance, oil resistance, heat resistance, and aging resistance.

Specification Parameters (Table)

Characteristics

• Excellent water resistance: can be immersed in water for a long time without falling off, discoloration or performance degradation.
  Good weather resistance: can resist the erosion of natural factors such as ultraviolet rays and temperature changes, and maintain the long-term stability of the coating.
  Excellent adhesion: can be closely combined with the substrate and is not easy to fall off.
  Good construction performance: easy to brush, fast drying, and the surface is smooth and flat after brushing.

Advantages

• Enhanced Durability: Extends the service life of architectural coatings.
• Cost Reduction: Lower cost compared to pure acrylic latex paints.
• Easy Application: Facilitates ease of application and high efficiency.
• Versatile Use: Suitable for various building materials, such as cement mortar, wood, concrete, etc.

Application Areas

• Architectural Coatings: For interior and exterior wall coatings, enhancing weatherability and durability.
• Metal Surface Latex Coatings: For protection and decoration of metal surfaces.
• Paper Adhesives: For bonding and impregnating paper, improving tensile strength, ring crush strength, and water resistance.
• Textile Auxiliaries: As a coating for fabrics, enhancing waterproofness and wear resistance.

Production Technology

The main raw materials for producing styrene-acrylic emulsion include styrene, acrylate monomers (such as methyl acrylate, ethyl acrylate, etc.), emulsifiers (such as sodium dodecyl sulfate), initiators (such as potassium persulfate), and water. The production process includes reactor cleaning, heating, monomer and initiator dripping, holding reaction, cooling, and discharging. During production, attention should be paid to temperature control, monomer dripping speed, and safety measures.

Theory

Styrene-acrylic emulsion is obtained through emulsion copolymerization of styrene and acrylate monomers. The introduction of styrene segments into the copolymer enhances the paint film's water resistance, alkaline resistance, hardness, stain resistance, and chalking resistance. Styrene-acrylic emulsion exhibits excellent transparency, film-forming properties, oil resistance, weatherability, and mechanical stability, making it an important raw material in coatings, adhesives, and other fields.

Service

Pre-sales consultation, mid-sales guidance, and post-sales technical support are provided. Customized services, including coating formula adjustments and construction technical training, are available based on customer needs.

Packaging & Storage

• Packaging: Typically packaged in 50kg drums.
• Storage: Should be stored in a warehouse at 5～30℃, avoiding high temperatures, direct sunlight, and humid conditions. Keep the packaging sealed to prevent air and moisture ingress.

Precautions

• Before Construction: Ensure the coating surface is clean, free of grease, dust, and other contaminants.
• During Construction: Strictly follow the manufacturer's guidelines for mixing the coating, use appropriate application tools and techniques to ensure uniform coating.
• After Construction: Allow the coating sufficient time to level and dry, preventing defects caused by excessive drying speed.
