It is a colorless, flammable liquid with a characteristic pungent, acrid odor. As a key acrylic monomer, it is widely used in the synthesis of polymers and copolymers for industrial and commercial applications.

Key Applications

Polymer Synthesis: The most critical application is as a monomer for producing acrylic polymers and copolymers, such as polybutyl acrylate (PBA), acrylate-styrene copolymers, and acrylate-vinyl acetate copolymers. These materials are the core of water-based paints, coatings, and adhesives, imparting flexibility, weather resistance, and adhesion.

Textile & Leather Industry: Used in the production of textile sizing agents, leather finishing agents, and waterproof coatings, improving fabric softness and leather durability.

Adhesives & Sealants: A key component in pressure-sensitive adhesives (PSAs), construction sealants, and industrial adhesives, enhancing bond strength and flexibility.

Plasticizers & Modifiers: Acts as a modifier for plastics (e.g., PVC) to improve impact resistance and processing performance; also used in the synthesis of functional polymers for biomedical and electronic applications.
