Description

2-Propenoic Acid, Polymer With Ethenyl Acetate And 2-Methylpropyl 2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This terpolymer combines the distinct properties of acrylic acid, vinyl acetate, and isobutyl methacrylate 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 performance. The compound is supplied under CAS No. 70776-46-4.

Application

• Industrial and Protective Coatings: Used as a key binder or additive to improve adhesion to difficult substrates, flexibility, and durability in metal, plastic, and wood coatings.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component in tape and label adhesives, offering a tunable balance of tack, peel strength, and shear resistance.
• Construction Sealants and Caulks: Imparts excellent weatherability, UV resistance, and elastic recovery in formulations for joints and gaps.
• Textile and Leather Finishes: Provides durable, flexible films for coatings and binders that enhance fabric hand-feel, water repellency, and abrasion resistance.
• Paper Coatings: Used to improve surface gloss, printability, and barrier properties of paper and paperboard.
• Specialty Inks: Enhances pigment binding, substrate adhesion, and rub resistance in flexographic and gravure printing inks.

Quality Control

Our 2-Propenoic Acid, Polymer With Ethenyl Acetate And 2-Methylpropyl 2-Propenoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as molecular weight distribution, monomer content, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain polymer stability.
