Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethyl 2-Propenoate, Methyl 2-Methyl-2-Propenoate And 2-Propenenitrile is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties derived from its constituent monomers, including hardness, chemical resistance, and film-forming capabilities. It is essential for manufacturers in the coatings, adhesives, and specialty plastics sectors seeking to enhance product durability and performance.

Application

• Industrial Coatings Binder: Used as a primary film-forming agent in solvent-based and high-solids coatings for metal, plastic, and wood substrates, providing excellent adhesion and weather resistance.
• Adhesive Formulations: Serves as a key component in pressure-sensitive adhesives (PSAs) and structural adhesives, contributing to tack, peel strength, and cohesion.
• Textile and Leather Finishing: Applied in coatings and finishes to impart water repellency, abrasion resistance, and a durable hand feel to fabrics and leather goods.
• Printing Inks: Utilized in the formulation of specialty printing inks, including those for plastics and foils, to improve gloss, rub resistance, and substrate adhesion.
• Paper Coating: Enhances the surface properties of paper and paperboard, improving printability, gloss, and water resistance in packaging applications.
• Sealants and Caulks: Acts as a polymeric base in elastomeric sealants, providing flexibility, durability, and resistance to environmental degradation.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Every batch is characterized for critical parameters including solid content, viscosity, glass transition temperature (Tg), and acid value to ensure consistent performance in your formulations. Comprehensive Certificates of Analysis (COA) documenting these specifications are available upon request, supporting compliance with relevant industry standards.

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, ensure containers are properly sealed to prevent skin formation or changes in viscosity.
