Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethenylbenzene, Ethyl 2-Propenoate And 2-Hydroxyethyl 2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver a robust balance of properties. This versatile polymer is engineered to provide excellent adhesion, durability, and chemical resistance in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive coatings, and corrosion-resistant finishes due to its strong adhesion and weatherability.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component for labels, tapes, and graphic films, offering a tunable balance of tack, peel strength, and cohesion.
• Textile and Leather Finishes: Imparts durable, flexible, and water-resistant coatings to fabrics, nonwovens, and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and moisture barrier properties of paperboard and packaging materials.
• Construction Chemicals: Incorporated into sealants, caulks, and tile adhesives to improve flexibility, bond strength, and longevity.
• Specialty Inks: Used as a resin in flexographic and gravure inks for packaging, providing good pigment wetting and film formation.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for your formulations. Key parameters such as solid content, viscosity, pH, glass transition temperature (Tg), and monomer residue are rigorously monitored. A Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your technical requirements.

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 exposure to extreme heat or freezing conditions to prevent product separation or degradation. Keep away from strong oxidizing agents.
