Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene, 2-Hydroxyethyl 2-Propenoate And 2-Methyl-2-Propenoic Acid CAS NO 63251-47-8 is a specialized multi-component copolymer designed for high-performance applications. This engineered polymer combines the properties of its constituent monomers to deliver exceptional durability, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and advanced materials sectors seeking to enhance product performance. Its tailored structure makes it suitable for demanding industrial environments where standard polymers may fail.

Application

• Industrial and Protective Coatings: Used as a binder or resin component in high-performance paints, marine coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a key polymer backbone in structural adhesives, pressure-sensitive adhesives (PSAs), and construction sealants for superior bonding strength.
• Textile and Leather Finishing: Employed in coatings and binders for textiles, synthetic leather, and non-woven fabrics to improve water resistance and durability.
• Paper and Packaging Coatings: Functions as a coating polymer to provide barrier properties, gloss, and printability for specialty papers and packaging materials.
• Automotive Components: Utilized in underbody coatings, interior trim adhesives, and other components requiring toughness and environmental resistance.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics (FRP) and other composite systems.

Quality Control

Our production of this specialty copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer residue, molecular weight distribution, viscosity, and solids content are rigorously monitored. Certificates of Analysis (COA) detailing lot-specific specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption or skin formation.
