Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With 2-Ethylhexyl 2-Propenoate, 2-Hydroxyethyl 2-Methyl-2-Propenoate And Methyl 2-Methyl-2-Propenoate CAS NO 74508-30-8 is a specialized acrylic copolymer designed to deliver a balanced profile of performance characteristics. This multi-monomer polymer is engineered to provide excellent film formation, adhesion, and durability, making it a versatile and high-performance raw material for demanding industrial formulations. It is primarily needed by manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product resilience and functionality.

Application

• Industrial and Protective Coatings: Used as a key binder in metal, wood, and plastic coatings requiring excellent weather resistance, gloss, and hardness.
• Adhesives and Sealants: Serves as a primary polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives for strong, flexible bonds.
• Printing Inks: Imparts superior pigment wetting, rub resistance, and adhesion to various substrates in flexographic and gravure inks.
• Textile and Leather Finishes: Applied as a finishing agent to provide durable water repellency, soft hand feel, and abrasion resistance.
• Paper Coatings: Enhances the surface strength, printability, and gloss of coated paper and paperboard.
• Specialty Additives: Utilized as a rheology modifier or film-forming agent in caulks, putties, and other construction chemicals.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against stringent in-house specifications for critical parameters such as solids content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these results 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 heat. Keep away from strong oxidizing agents.
