Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Butyl 2-Propenoate And 2-Hydroxyethyl 2-Propenoate CAS NO 71832-60-5 is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming properties and durability. This specialized polymer is engineered to provide a critical balance of flexibility, adhesion, and chemical resistance for demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: A key film-forming agent in solvent-based coatings for metal, wood, and plastic substrates, offering excellent weatherability and corrosion resistance.
• Adhesive Formulations: Used as a primary binder in pressure-sensitive adhesives (PSAs) and structural adhesives, providing strong initial tack and cohesive strength.
• Automotive Refinish and OEM Coatings: Imparts high gloss, color retention, and resistance to fuels and chemicals in automotive paint systems.
• Industrial Sealants and Caulks: Enhances elasticity, adhesion, and durability in construction and maintenance sealants.
• Printing Inks: Serves as a resin component in specialty printing inks, improving pigment wetting, gloss, and substrate adhesion.
• Textile and Leather Finishes: Applied as a coating or binder to provide water repellency, abrasion resistance, and a soft hand feel.

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 including monomer residue, molecular weight distribution, viscosity, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) documenting all critical 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 temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. Ensure containers are kept tightly sealed when not in use to prevent solvent loss and skin formation.
