Description

Butanedioic Acid, Methylene-, Polymer With Butyl 2-Propenoate, Ethyl 2-Propenoate, n-(Hydroxymethyl)-2-Propenamide And 2-Propenamide is a specialized multi-component copolymer designed to deliver enhanced performance in demanding industrial applications. This engineered polymer combines the structural benefits of a methylene succinic acid backbone with the functional versatility of acrylate and acrylamide monomers, creating a material with excellent film-forming, adhesive, and cross-linking properties. It is a critical raw material for formulators in the coatings, adhesives, and textile industries seeking to improve product durability, chemical resistance, and binding strength.

Application

• Industrial Coatings Binder: Serves as a high-performance film-forming agent and cross-linker in water-based or solvent-based industrial coatings, providing enhanced hardness, gloss, and resistance to chemicals and weathering.
• Adhesive Formulations: Used as a key component in structural and pressure-sensitive adhesives (PSAs) to improve tack, peel strength, and cohesion, particularly for labels, tapes, and laminates.
• Textile Finishing & Sizing: Functions as a durable polymer binder in textile finishing to impart wrinkle resistance, stiffness, or water repellency, and as a sizing agent to protect yarns during weaving.
• Paper Coating & Saturation: Enhances the strength, printability, and barrier properties of paper and paperboard when used in coating formulations or as a saturant.
• Leather Finishing: Applied in topcoat formulations for leather to improve surface finish, flexibility, and resistance to abrasion and solvents.
• Cross-linking Agent for Resins: Utilized to modify and cross-link other polymer systems, such as acrylics or urethanes, to enhance their thermal stability and mechanical properties.
