About Butyl Acrylate Monomer
Butyl Acrylate Monomer is a clear, colorless liquid with a characteristic fruity odor. It is the butyl ester of acrylic acid and features high reactivity due to its unsaturated bond. BAM is widely used as a soft monomer in copolymer formulations, where it imparts flexibility, adhesion, and resistance to environmental factors in final products.

Applications / Uses
BAM is a key monomer for producing a wide range of copolymers:

Paints & Coatings: Used in architectural and industrial coatings to enhance flexibility and weather resistance.
Adhesives & Sealants: Improves elasticity and tack in pressure-sensitive adhesives and construction sealants.
Textiles: Found in finishes and binders that provide softness, durability, and water resistance.
Plastics & Films: Acts as a component in soft, impact-resistant polymers and specialty films.
Construction: Utilized in waterproofing membranes, grouts, and flexible cement modifiers.
Paper Industry: Applied in paper coatings and additives for improved strength and printability.

• Storage & Handling
• Store in tightly closed, inhibitor-stabilized containers in a cool, dry, and well-ventilated place.
• Keep away from heat, flames, and strong oxidizers — BAM is flammable and prone to polymerization.
• Wear protective gloves, goggles, and suitable clothing to avoid contact with skin or eyes.
• Ensure proper ventilation or use respiratory protection to prevent vapor inhalation.
