Description

2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate, ethenylbenzene, 2-ethylhexyl 2-propenoate, methyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate) is a specialized multi-component acrylic copolymer designed to deliver a balanced profile of performance characteristics. This polymer is engineered to provide excellent film formation, adhesion, and durability, making it a critical raw material for high-performance industrial coatings and adhesives. It is essential for formulators in the paints, coatings, and construction industries seeking to enhance product longevity and resistance properties.

Application

• Architectural and Decorative Coatings: Used as a key binder in exterior and interior paints to provide weatherability, water resistance, and color retention.
• Industrial Maintenance Coatings: Formulated into protective coatings for metal, concrete, and other substrates to guard against corrosion and chemical exposure.
• Adhesives and Sealants: Serves as a base polymer in construction adhesives, caulks, and sealants, offering strong adhesion and flexibility.
• Printing Inks: Utilized in the formulation of overprint varnishes and specialty inks to improve gloss, rub resistance, and drying properties.
• Textile and Leather Finishes: Applied as a coating or binder to provide durable, flexible finishes with enhanced handle and appearance.
• Primers and Undercoats: Acts as a foundational layer to promote adhesion of topcoats to difficult substrates.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like viscosity, solids content, and glass transition temperature (Tg). Certificates of Analysis (COA) are provided with each shipment, detailing specifications for key properties. While typically supplied as an industrial-grade material, production can be aligned with relevant ISO standards upon request to meet specific customer and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (typically 15-25°C). Keep away from heat sources and open flame. Ensure containers are kept tightly sealed when not in use to prevent skin formation or changes in viscosity due to solvent evaporation or moisture uptake.
