Description

2-Propenoic Acid, 2-Methyl-, 2-Hydroxyethyl Ester, Polymer With 1,3-Butadiene And Ethenylbenzene is a high-performance, multi-component polymer designed for advanced material science applications. This specialized copolymer combines the toughness and flexibility of butadiene with the adhesion and durability characteristics of styrene and methacrylate monomers. It is engineered to deliver exceptional performance as a film-forming agent, binder, or modifier in demanding industrial formulations. Key industries that rely on this polymer include coatings, adhesives, sealants, and elastomers (CASE), where it enhances product resilience, adhesion, and environmental resistance.

Application

• Industrial and Protective Coatings: Acts as a primary film-forming resin or additive to improve flexibility, impact resistance, and adhesion to various substrates in metal, wood, and plastic coatings.
• Pressure-Sensitive Adhesives (PSAs): Used as a key polymer component to balance tack, peel strength, and shear resistance in label and tape formulations.
• Sealants and Caulks: Imparts durability, elasticity, and weather resistance to construction and automotive sealant products.
• Textile and Leather Finishes: Serves as a binder or coating to provide a durable, flexible, and water-resistant finish to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and water resistance of paperboard and packaging materials.
• Impact Modifier for Plastics: Incorporated into rigid plastic matrices (e.g., PVC, engineering plastics) to improve toughness and resistance to cracking.
• Specialty Inks: Used in flexographic and gravure inks to promote adhesion and film integrity on non-porous surfaces.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer conversion, molecular weight distribution, particle size (for latex forms), and residual monomer content are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request. We support our global clients by ensuring our products and processes align with relevant industry and regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. For liquid latex or solution forms, store in a cool, well-ventilated area at temperatures between 15-25°C (59-77°F). Prevent freezing and excessive heat. For solid forms, store in a dry place. Keep away from strong oxidizing agents and incompatible materials. Shelf life is typically 12 months from the date of manufacture when stored under recommended conditions.
