Description

2-Propenoic Acid, 2-Methyl-, Polymer With 1,1-Dimethylethyl 2-Propenoate And Ethyl 2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional film-forming, adhesion, and durability properties. This specialized polymer is engineered to meet the demanding requirements of advanced coating and adhesive formulations, offering a balance of flexibility, chemical resistance, and weatherability. It is a critical raw material for manufacturers in the paints & coatings, pressure-sensitive adhesives, and industrial sealants sectors seeking to enhance product performance and longevity.

Application

• Architectural and Industrial Coatings: Used as a key binder in exterior paints, metal coatings, and wood finishes for enhanced gloss, durability, and resistance to weathering and chemicals.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component in tapes, labels, and graphic films, providing excellent tack, peel adhesion, and cohesive strength.
• Industrial Sealants and Caulks: Imparts flexibility, adhesion, and long-term stability to sealants used in construction and automotive applications.
• Printing Inks: Utilized in overprint varnishes and ink formulations to improve gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Acts as a finishing agent to provide water repellency, softness, and abrasion resistance to fabrics and leather goods.
• Plastic and Rubber Modification: Employed as an impact modifier or processing aid to enhance the mechanical properties and surface characteristics of polymer blends.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 high temperatures or direct heat sources to maintain product stability and prevent premature polymerization or changes in viscosity.
