Description

2-Propenoic Acid, 2-Methyl-, 2-Hydroxyethyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene, Methyl 2-Methyl-2-Propenoate And 2-Propenoic Acid CAS NO 55993-98-1 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: Used as a key binder in high-performance metal primers, automotive topcoats, and corrosion-resistant industrial finishes.
• Architectural Paints: Serves as a film-forming agent in exterior and interior paints, providing weatherability, scrub resistance, and gloss control.
• Adhesives and Sealants: Imparts strong adhesion to diverse substrates (metal, plastic, wood) in pressure-sensitive, structural, and assembly adhesives.
• Printing Inks: Acts as a resin component in overprint varnishes and specialty inks, offering fast drying times and substrate compatibility.
• Textile and Leather Finishes: Employed in coatings and binders to provide water repellency, abrasion resistance, and a soft hand feel.
• Plastic Modifiers: Used to improve the impact resistance, surface hardness, and processing characteristics of thermoplastic compounds.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for formulators. While specifications vary by grade, our standard industrial-grade material is characterized by key parameters such as solids content, viscosity, acid value, and glass transition temperature (Tg). A comprehensive Certificate of Analysis (COA) detailing these and other relevant specifications is provided with every shipment to guarantee product integrity and performance.

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). Keep away from heat sources and open flame. For long-term storage, maintain under an inert atmosphere if supplied as a solution to prevent skinning or polymerization.
