Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, 2-Hydroxyethyl 2-Propenoate And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver a balance of properties including adhesion, flexibility, and chemical resistance. This polymer is engineered to provide a durable, clear film-forming matrix that is essential for demanding industrial and specialty coating applications. It is a critical raw material for formulators in the paints & coatings, adhesives & sealants, and construction chemicals sectors seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a primary binder in metal primers, topcoats, and anti-corrosive paints for machinery, automotive parts, and structural steel.
• Architectural Paints: Serves as a key component in exterior and interior wall paints, providing excellent weatherability, scrub resistance, and adhesion to various substrates.
• Adhesives and Sealants: Imparts flexibility and strong bonding characteristics to pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives.
• Textile and Leather Finishes: Employed in coatings and binders to provide a soft hand feel, durability, and water resistance to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and moisture barrier properties of paperboard and packaging materials.
• Specialty Inks: Used as a resin in flexographic and gravure printing inks for films and foils, offering good pigment wetting and adhesion.

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 solids content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution are rigorously monitored. Certificates of Analysis (COA) documenting all critical specifications are provided with every 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, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid exposure to extreme heat or freezing conditions. Keep away from strong oxidizing agents. For specific storage recommendations based on the product form (e.g., aqueous dispersion vs. solid), please refer to the Safety Data Sheet (SDS).
