Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Methyl-2-Propenoate, Methyl 2-Methyl-2-Propenoate And 2-Propenenitrile CAS NO 26587-20-2 is a high-performance, multi-component acrylic copolymer engineered for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its constituent monomers, including acrylic acid, butyl methacrylate, methyl methacrylate, and acrylonitrile. It is primarily sought after by manufacturers in the coatings, adhesives, and sealants industries for its excellent film-forming characteristics, adhesion, and durability.

Application

• Industrial and Protective Coatings: Used as a key binder in solvent-based or high-solids coatings for metal, plastic, and wood substrates, providing corrosion resistance and weatherability.
• Adhesive Formulations: Serves as a primary resin in pressure-sensitive adhesives (PSAs), laminating adhesives, and structural adhesives, offering strong bonding and flexibility.
• Automotive Finishes: A component in primer, basecoat, or clearcoat systems for automotive refinish and OEM applications, contributing to gloss and chemical resistance.
• Textile and Leather Finishes: Employed in coatings and binders for textiles, non-wovens, and leather to improve handle, durability, and water repellency.
• Printing Inks: Used in the formulation of specialty printing inks to enhance adhesion to various films and foils and improve rub resistance.
• Construction Sealants and Caulks: Imparts flexibility, adhesion, and longevity to sealants used in building and construction.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistent performance parameters such as molecular weight distribution, solids content, viscosity, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing these specifications 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, 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 or skin formation.
