Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene, 2-hydroxyethyl 2-propenoate, methyl 2-methyl-2-propenoate and oxiranylmethyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics, making it a critical raw material for advanced coating systems. It is primarily utilized by formulators in the paints, coatings, adhesives, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: As a key binder in high-performance paints and varnishes for metal, wood, and plastic substrates, providing corrosion resistance and weatherability.
• Automotive Refinish and OEM Coatings: Used in primer, basecoat, and clearcoat formulations to achieve excellent gloss, adhesion, and scratch resistance.
• Adhesives and Sealants: Serves as a primary component in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, offering strong bonding and flexibility.
• Printing Inks: Employed in the formulation of overprint varnishes and specialty inks to improve gloss, rub resistance, and drying properties.
• Textile and Leather Finishes: Used as a coating or finishing agent to provide water repellency, softness, and durability to fabrics and leather goods.
• Cross-linking Polymer Systems: The oxiranylmethyl (glycidyl) groups present in the copolymer allow for cross-linking with various curing agents (e.g., amines, acids) to create thermoset networks with enhanced mechanical and chemical properties.

Quality Control

Our production of this advanced 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, epoxy equivalent weight, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and formulation processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Avoid exposure to extreme heat, direct sunlight, and sources of ignition. Keep containers tightly sealed when not in use to prevent skinning or changes in viscosity due to solvent evaporation or moisture absorption.
