Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene, (1-Methylethenyl)Benzene And Methyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties derived from its constituent monomers, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty plastics industries seeking to enhance product durability and performance.

Application

• Industrial Coatings Binder: Used as a primary film-forming agent in protective and decorative coatings for metal, wood, and plastic substrates, providing weatherability and hardness.
• 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 Finishes: Applied in coatings and backings to impart water resistance, flexibility, and a durable hand feel.
• Paper Coating: Enhances the surface gloss, printability, and barrier properties of specialty papers and paperboard.
• Caulks and Sealants: Provides elasticity, adhesion, and longevity in construction and automotive sealant formulations.
• Plastic Modifier: Used as an impact modifier or processing aid to improve the toughness and flow characteristics of engineering plastics.

Quality Control

Every batch of our acrylic copolymer is manufactured under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) that detail key parameters such as solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. Our production adheres to ISO 9001 standards, ensuring consistency and reliability for your formulation 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, ensure containers are sealed to prevent skin formation or changes in viscosity.
