Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Ethyl 2-Propenoate, Methyl 2-Propenoate And 2-Propenoic Acid CAS NO 67923-67-5 is a high-performance acrylic copolymer designed for demanding industrial applications. This multi-monomer polymer offers a versatile balance of properties, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty polymers sectors seeking to enhance product durability and performance.

Application

• Industrial Coatings Binder: Used as a primary film-forming agent in solvent-based and high-solid coatings for metal, plastic, and wood substrates, providing durability and gloss.
• Adhesive Formulations: Serves as a key component in pressure-sensitive adhesives (PSAs), laminating adhesives, and construction sealants, offering strong bonding and flexibility.
• Printing Inks: Employed in the formulation of overprint varnishes and specialty inks to improve abrasion resistance, gloss, and drying characteristics.
• Textile and Leather Finishes: Used in coatings and finishes to impart water resistance, softness, and improved handle to fabrics and leather goods.
• Plastic Modifier: Acts as an impact modifier or processing aid to enhance the toughness and surface characteristics of compounded plastics.
• Caulks and Sealants: Provides elasticity, adhesion, and weather resistance in high-performance construction and automotive sealants.

Quality Control

Our acrylic copolymer is manufactured under a strict quality management system. Every batch undergoes rigorous testing for critical parameters including solids content, viscosity, glass transition temperature (Tg), and acid value to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) documenting full specifications are available upon request.

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, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
