Description

Butanedioic Acid, Methylene-, Polymer With 1,3-Butadiene, Ethenylbenzene, 2-Hydroxyethyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate is a specialized multi-component copolymer designed for high-performance applications. This engineered polymer combines the properties of its constituent monomers to deliver a unique balance of adhesion, flexibility, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and functionality. The material is supplied under strict quality control to ensure batch-to-batch consistency for industrial manufacturing.

Application

• Industrial and Protective Coatings: Used as a resin component in high-durability paints, marine coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a key polymer backbone in structural adhesives, pressure-sensitive adhesives (PSAs), and elastic sealants.
• Textile and Leather Finishing: Employed in coatings and binders to provide water resistance, flexibility, and improved handle to fabrics and leather.
• Paper and Packaging Coatings: Enhances the barrier properties, printability, and gloss of coated papers and packaging materials.
• Polymer Modification: Acts as an impact modifier or compatibilizer in plastic and rubber compounds to improve toughness and processing.
• Construction Chemicals: Incorporated into cement modifiers, tile adhesives, and waterproofing membranes for enhanced performance.

Quality Control

Our production of this specialty copolymer adheres to rigorous quality testing protocols to ensure it meets precise specifications for viscosity, solids content, acid value, and monomer residue levels. Each batch is manufactured under controlled conditions and is supported by a comprehensive Certificate of Analysis (COA) available upon request. We are committed to supplying a product with the consistency and purity required for demanding industrial formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flames. For long-term storage, ensure the container is properly sealed to prevent skin formation or changes in viscosity.
