Styrene-acrylic emulsion

1. Product overview

Styrene Acrylic Emulsion is a polymer copolymer produced by the emulsion polymerization of Styrene and acrylic monomers (such as butyl acrylate and methyl methacrylate). The emulsion has excellent film forming property, weather resistance, adhesion and chemical stability, and is widely used in coating, adhesive, textile, paper and other fields.

2. Product features

Feature | Advantage Description |

| high adhesion | has excellent bonding properties for a variety of substrates (such as wood, metal, plastic, concrete) |

| water and alkali resistant | Strong water resistance, suitable for high humidity environment; Good alkaline resistance, can be used for cement substrate |

| Excellent flexibility | Acrylic component provides good toughness and reduces the risk of film cracking |

| Environmental protection low VOC | Water-based system, no organic solvents, in line with environmental regulations (such as GB 18582-2020) |

| good stability | excellent mechanical stability, freeze-thaw stability, storage period ≥12 months |

3. Typical applications

- Architectural coatings: interior and exterior latex paint, waterproof paint, real stone paint binder

- Industrial coatings: metal anti-corrosion primer, wood paint, floor paint

- Adhesive: composite adhesive for packaging, non-woven binder, tile adhesive

- Textile/paper: fabric coating, paper surface sizing agent

- Ink: Water-based ink connection material, providing high gloss and wear resistance
