Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, Ethenylbenzene 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, including excellent film formation, adhesion, and chemical resistance, making it a critical raw material for advanced coating systems. It is primarily utilized by formulators in the paints & coatings, adhesives, and construction materials industries seeking to enhance product durability and performance.

Application

• Architectural and Industrial Paints & Coatings: Serves as a key binder in water-based or solvent-based formulations, providing weatherability, gloss, and scrub resistance.
• Industrial and Construction Adhesives: Used in pressure-sensitive adhesives (PSAs) and sealants for its strong adhesion to diverse substrates and flexibility.
• Protective and Marine Coatings: Formulated into coatings that require robust resistance to corrosion, chemicals, and UV degradation.
• Textile and Leather Finishes: Acts as a finishing agent to impart water repellency, softness, and durability to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and moisture barrier properties of paper and cardboard.
• Caulks and Joint Compounds: Provides binding and film-forming properties in construction-grade mastics and fillers.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solid content, viscosity, pH, and glass transition temperature (Tg). Comprehensive Certificates of Analysis (COA) documenting these specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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.
