Core Product Features

1. Superior Copolymerization Performancen-Butyl Acrylate can easily copolymerize with methyl acrylate, styrene, vinyl acetate and other monomers. It effectively improves the flexibility, ductility and film-forming property of polymer products, overcoming the brittleness defect of rigid resin materials.

2. Excellent Weather & Water ResistanceThe monomer endows finished products with outstanding hydrophobicity, anti-aging, anti-UV and stain-resistant properties. It maintains stable performance under extreme temperature changes and humid environments, greatly extending the service life of coatings and adhesives.

3. Strong Adhesion & FlexibilityWith a low glass transition temperature (Tg), BA-based polymers deliver excellent bonding strength on metal, plastic, wood, fabric and paper surfaces. The finished materials remain soft and crack-resistant at low temperatures.

4. Stable Industrial Grade QualityStrict distillation and impurity removal processes ensure low moisture, low acidity and high stability. The standardized MEHQ inhibitor formula prevents self-polymerization during transportation and storage, meeting mass industrial production requirements.

Wide Industrial Applications

1. Paints & Coatings Industry

It is the key monomer for architectural coatings, automotive coatings, industrial anti-corrosion coatings and water-based emulsion paints. It enhances coating adhesion, flexibility, wear resistance and weatherability, making paint films smooth, durable and non-peeling.

2. Adhesives & Sealants Industry

Widely used in pressure-sensitive adhesives, water-based glues, industrial sealants and caulks. It improves the initial viscosity, permanent adhesion and low-temperature resistance of adhesives, suitable for packaging, automotive and construction bonding scenarios.

3. Textile & Leather Finishing

Applied in textile printing and dyeing emulsions, fabric softeners and leather finishing agents. It upgrades fabric waterproofness, wrinkle resistance and wear resistance, and makes leather surfaces smooth, elastic and scratch-resistant.

4. Paper Making Industry

Used as paper surface sizing agents and reinforcing additives. It effectively improves paper surface smoothness, tensile strength and water permeability resistance, optimizing paper printing performance and durability.

5. Plastic & Polymer Modification

Serves as an impact modifier and processing aid for thermoplastics. It is commonly used in EBA copolymer production to enhance the toughness and processability of plastic products, widely applied in modified plastics and synthetic rubber industries.

6. Printing Ink Industry

Used in water-based ink emulsions to improve ink film flexibility, substrate adhesion and drying performance, ensuring clear printing patterns and anti-falling effects.
