Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,3-Butadiene, Butyl 2-Propenoate And Ethenylbenzene is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer combines the durability of butadiene, the weatherability of acrylic esters, and the rigidity of styrene to deliver a robust material matrix. It is primarily utilized in the formulation of advanced adhesives, coatings, and sealants where a balance of flexibility, adhesion, and chemical resistance is critical. This product, identified by CAS No. 25101-28-4, is essential for manufacturers seeking reliable polymeric raw materials for high-value end products.

Application

• Pressure-Sensitive Adhesives (PSAs): A key component for tapes, labels, and graphic films requiring excellent tack and peel adhesion.
• Industrial and Protective Coatings: Used in formulations for metal primers, appliance finishes, and corrosion-resistant paints.
• Construction Sealants and Caulks: Provides flexibility, durability, and strong substrate bonding for joint sealants in buildings and infrastructure.
• Textile and Non-Woven Binders: Serves as a durable binder for fiber bonding in non-woven fabrics and textile coatings.
• Leather and Synthetic Leather Finishes: Imparts a flexible, wear-resistant, and aesthetically pleasing topcoat.
• Paper and Packaging Coatings: Enhances the strength, water resistance, and printability of paperboard and packaging materials.
• Impact Modifiers for Plastics: Used to improve the toughness and impact resistance of rigid plastic compounds.

Quality Control

Our production of this advanced 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, glass transition temperature (Tg), and solids content are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance with relevant industry and safety standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid freezing and prolonged exposure to elevated temperatures to prevent changes in viscosity or polymer properties. Keep away from open flames and sources of ignition.
