What is Butyl Acrylate Monomer?
Butyl Acrylate Monomer is a colourless, flammable liquid with a characteristic fruity odour and the chemical formula CH2=CHCOOC4H9. It is one of the most widely used acrylate monomers in the production of acrylic polymer emulsions, prized for the flexibility, low glass transition temperature, and excellent weatherability it imparts to the resulting copolymers. As a key comonomer alongside acrylic acid, methyl methacrylate, and other acrylates, Butyl Acrylate is fundamental to the modern acrylic polymer industry.
Polychem Industries supplies Butyl Acrylate Monomer to acrylic emulsion manufacturers, paint and coating producers, adhesive formulators, and textile finishing companies across India and internationally. Its ability to impart softness and flexibility to acrylic copolymers, balanced against the hardness contributed by comonomers like methyl methacrylate, makes it an essential building block across the water-based coatings and adhesives industry.
Safety & Handling Notice
Butyl Acrylate Monomer is a flammable liquid with a strong, characteristic odour that can cause skin, eye, and respiratory irritation. It can undergo exothermic polymerisation if exposed to heat or contaminants. Handle with full PPE including gloves, goggles, and adequate ventilation. Store with MEHQ inhibitor and away from heat sources and oxidising agents.

Applications & Uses
Acrylic Emulsions & Paints
The largest application. Butyl Acrylate is copolymerised with other acrylic monomers to produce the acrylic emulsion polymers used as the binder in water-based architectural and industrial paints, contributing flexibility and good film-forming properties.
Pressure-Sensitive Adhesives
Used extensively in the production of acrylic pressure-sensitive adhesives for tapes, labels, and sticky-note products, where its low glass transition temperature provides the necessary tack and peel adhesion characteristics.
Textile & Leather Coatings
Used in textile finishing and leather coating formulations, providing flexibility, softness, and durability to the coated fabric or leather surface while maintaining good adhesion to the substrate.
Paper Coatings
Used in the production of acrylic latex binders for paper coating applications, contributing flexibility and binding strength to coated paper and packaging products.
Construction & Sealants
Used in acrylic-based construction sealants and caulks, where its flexibility contributes to the elastomeric properties needed for effective sealing and joint movement accommodation.
Specialty Copolymer Synthesis
Used as a key comonomer in the synthesis of various specialty acrylic copolymers tailored for specific performance requirements across coatings, adhesives, and polymer modification applications.
