Description

2-Propenoic Acid, 2-Methyl-, 2-(Dimethylamino)Ethyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene, Methyl 2-Methyl-2-Propenoate And 2-Propenoic Acid is a specialized acrylic copolymer designed for high-performance applications. This multi-component polymer offers a unique balance of properties derived from its constituent monomers, including film formation, adhesion, and cationic functionality. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability and performance. The compound is supplied under CAS No. 126895-95-2.

Application

• Industrial and Protective Coatings: Used as a key binder or additive to improve adhesion, corrosion resistance, and film integrity on metal, plastic, and composite substrates.
• Adhesives and Sealants: Serves as a base polymer for pressure-sensitive adhesives (PSAs), structural adhesives, and sealants, providing tack, cohesion, and bonding strength.
• Printing Inks and Overprint Varnishes: Imparts gloss, rub resistance, and rapid setting properties in flexographic, gravure, and specialty ink formulations.
• Textile and Leather Finishes: Applied as a coating or finishing agent to provide water repellency, soft hand feel, and durability to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances surface smoothness, printability, and barrier properties in paperboard and flexible packaging applications.
• Personal Care and Cosmetic Products: Utilized as a film-forming agent or fixative in hair sprays, mousses, and other styling products.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Every batch is characterized for critical parameters including monomer content, molecular weight distribution, viscosity, solids content, and ionic character to ensure consistent performance and batch-to-batch reproducibility. Comprehensive Certificates of Analysis (COA) detailing all specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (nitrogen blanket) is recommended to prevent oxidation and maintain product stability. Keep container tightly sealed when not in use to prevent skinning or moisture absorption.
