Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Ethyl 2-Propenoate And M CAS NO 40471-03-2 is a high-performance acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a critical balance of properties, including excellent film formation, adhesion, and chemical resistance. It is an essential raw material for manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance.

Application

• Industrial Coatings Binder: A key component in formulating high-performance industrial and maintenance paints, providing durability and weather resistance.
• Adhesive Formulations: Used in pressure-sensitive adhesives (PSAs) and structural adhesives to improve tack, peel strength, and cohesion.
• Textile and Leather Finishes: Serves as a binder and finishing agent to impart water resistance, flexibility, and a soft hand feel to treated fabrics and leathers.
• Paper Coating: Enhances the surface strength, printability, and gloss of coated paper and paperboard products.
• Sealant and Caulk Formulations: Provides elasticity, adhesion, and long-term weatherability in construction and automotive sealants.
• Specialty Inks: Used as a resin in flexographic and gravure inks to improve pigment binding and film properties.

Quality Control

Our acrylic copolymer is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against critical parameters including solid content, viscosity, glass transition temperature (Tg), and monomer residue levels. Certificates of Analysis (COA) documenting these specifications are available upon request 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, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
