Description

2-Propenoic acid, 2-methyl-, 2-hydroxyethyl ester, polymer with ethenylbenzene, methyl 2-methyl-2-propenoate, 2-methylpropyl 2-propenoate and oxiranylmethyl 2-methyl-2-propenoate CAS NO 119185-08-9 is a specialized multi-component acrylic copolymer designed to deliver a unique balance of properties for advanced coating and adhesive formulations. This polymer is engineered to provide exceptional durability, adhesion, and chemical resistance, making it a critical component for high-performance industrial applications. It is primarily utilized by formulators in the paints and coatings, industrial adhesives, and specialty resin sectors seeking to enhance product performance and longevity.

Application

• High-Performance Industrial Coatings: Used as a key resin binder in protective coatings for metal, automotive, and machinery, offering excellent weatherability and corrosion resistance.
• Advanced Adhesives and Sealants: Serves as a primary polymer in structural and pressure-sensitive adhesives (PSAs) requiring strong bonding and flexibility.
• Specialty Inks and Overprint Varnishes: Imparts gloss, scratch resistance, and rapid curing properties in graphic arts and packaging applications.
• Composite Materials: Acts as a matrix or modifier in fiber-reinforced plastics and other composite systems to improve mechanical strength and interfacial adhesion.
• UV-Curable Formulations: The oxiranylmethyl (glycidyl) component can facilitate crosslinking in radiation-curable coatings and inks for fast, low-energy curing processes.
• Textile and Leather Finishes: Provides durable, flexible, and water-resistant finishes for technical textiles and coated fabrics.

Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for formulators. Each lot is characterized for critical parameters including monomer residue, molecular weight distribution, viscosity, and functional group content. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can tailor quality protocols to meet specific customer or industry standards.

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 flames. The product is light-sensitive (store away from light) and should be handled to minimize prolonged exposure to air to prevent skinning or moisture uptake.
