Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Butyl 2-Propenoate, 2-Ethylhexyl 2-Propenoate And 2-Propenoic Acid CAS NO 42398-14-1 is a high-performance acrylic copolymer designed to deliver exceptional film-forming, adhesive, and protective properties. This versatile polymer is engineered to provide a critical balance of flexibility, durability, and chemical resistance for demanding industrial formulations. It is an essential raw material for manufacturers in the coatings, adhesives, and specialty chemical sectors seeking to enhance product performance and reliability.

Application

• Industrial and Protective Coatings: Used as a primary film-forming agent in metal primers, automotive underbody coatings, and corrosion-resistant finishes.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in the formulation of tapes, labels, and graphic films, offering excellent tack and peel strength.
• Textile and Leather Finishes: Provides durable, flexible coatings and binders that enhance water repellency, abrasion resistance, and hand feel.
• Printing Inks and Overprint Varnishes: Imparts gloss, adhesion, and rub resistance to inks and protective topcoats for packaging and publications.
• Caulks and Sealants: Acts as a polymeric base to improve flexibility, adhesion, and long-term weatherability in construction and automotive sealants.
• Industrial Binders and Sizing Agents: Utilized in non-woven fabrics, paper coating, and composite materials to improve strength and cohesion.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer residue, molecular weight distribution, viscosity, and acid value are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment 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 ambient temperatures (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, ensure containers are sealed to prevent skin formation or moisture absorption.
