Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Methyl-2-Propenoate, Methyl 2-Methyl-2-Propenoate And 2-(3-Oxazolidinyl)Ethyl 2-Methyl-2-Propenoate CAS NO 70892-90-9 is a specialized acrylic copolymer designed to deliver enhanced performance characteristics. This multi-monomer polymer is engineered to provide a unique balance of film-forming properties, adhesion, and chemical resistance, making it a critical component in advanced industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty chemical sectors seeking to improve product durability and functionality.

Application

• Industrial and Protective Coatings: Used as a key resin in high-performance coatings for metal, plastic, and wood substrates, offering excellent weatherability and corrosion resistance.
• Adhesives and Sealants: Serves as a primary binder in pressure-sensitive adhesives (PSAs), structural adhesives, and sealants, providing strong adhesion and flexibility.
• Printing Inks: Incorporated into formulations for flexographic and gravure inks to enhance gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Applied as a finishing agent to impart water repellency, softness, and durability to fabrics and leather goods.
• Paper Coatings: Used in barrier coatings and saturants to improve paper strength, printability, and resistance to water and grease.
• Specialty Additives: Functions as a rheology modifier or film-forming agent in construction chemicals, personal care products, and cleaning formulations.

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 characterized for critical parameters including monomer content, molecular weight distribution, viscosity, and functional group concentration. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product stability.
