Description

2-Propenoic acid, 2-methyl-, methyl ester, polymer with 1,3-butadiene, butyl 2-propenoate, ethenylbenzene and .alpha.-(2-methyl-1-oxo-2-propenyl)-.omega.-methoxypoly(oxy-1,2-ethanediyl) CAS NO 80338-13-2 is a specialized acrylic copolymer designed for high-performance applications. This multi-component polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a critical raw material for demanding industrial formulations. It is primarily utilized by manufacturers in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: As a key binder in high-durability paints, metal primers, and corrosion-resistant finishes for automotive, marine, and architectural applications.
• Pressure-Sensitive Adhesives (PSAs): Used in the formulation of tapes, labels, and graphic films due to its excellent tack and peel adhesion properties.
• Sealants and Caulks: Provides flexibility, adhesion, and weatherability in construction and automotive sealant formulations.
• Textile and Leather Finishes: Imparts water resistance, softness, and durability to fabrics and synthetic leather coatings.
• Paper and Packaging Coatings: Enhances gloss, printability, and barrier properties for high-quality paperboard and packaging materials.
• Industrial Binders: Serves as a robust binder for non-woven fabrics, fiber mats, and composite materials.

Quality Control

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

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/59-77°F). This product is easily oxidized (store under inert atmosphere). Keep away from heat, sparks, and open flame. For long-term storage, consider blanketing with an inert gas such as nitrogen to preserve product integrity.
