Styrene-Acrylic Emulsion

1. Product overview

Styrene-Acrylic Emulsion (Styrene-Acrylic Emulsion) The emulsion has excellent film-forming properties, weatherability, adhesion and chemical stability, and is widely used in coatings, adhesives, textiles, paper and other fields.  

2. Product Characteristics 

| Characteristics | Advantage Description |  

|-------------------|-----------------------------------------------------------------------------|  

| High Adhesion | Excellent adhesion to a wide range of substrates (such as wood, metal, plastics, concrete) |  

| Water and Alkali Resistance | High water resistance, suitable for high humidity environment; good alkali resistance, can be used on cement substrate |  

| Acrylate component provides good toughness and reduces the risk of film cracking.  

| Low VOC | Water-based system, no organic solvents, in line with environmental regulations (such as GB 18582-2020) | Good stability | Mechanical and mechanical stability  

| Good stability | Excellent mechanical stability, freeze-thaw stability, storage period ≥ 12 months |  

3. Typical applications

- Architectural coatings: interior and exterior wall emulsion paints, waterproof coatings, real stone paint binder

- Industrial coatings: metal anticorrosive primer, wood paint, floor paint.  

- Adhesives: packaging composite adhesive, non-woven fabric binder, tile adhesive  

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

- Inks: water-based ink connectors providing high gloss and abrasion resistance
