Description

2-Propenoic Acid, 2-Methyl-, Oxiranylmethyl Ester, Polymer With Ethenylbenzene And 2-Propenoic Acid CAS NO 38808-51-4 is a high-performance, multi-functional polymer designed for advanced coating and adhesive formulations. This specialized copolymer combines the toughness and chemical resistance of styrene with the adhesion and crosslinking potential of acrylic and glycidyl methacrylate monomers. It is essential for manufacturers seeking to enhance the durability, adhesion, and environmental resistance of their industrial products. Key target industries include automotive, construction, and specialty chemical production.

Application

• High-Performance Industrial Coatings: Used as a key binder in protective coatings for metal, concrete, and plastics, providing excellent weatherability and chemical resistance.
• Structural and Assembly Adhesives: Serves as a critical component in epoxy-acrylic hybrid adhesives for automotive, aerospace, and construction applications, offering strong bonding and flexibility.
• Can and Coil Coatings: Formulated into coatings for food/beverage cans and pre-coated metal coils (coil coatings) due to its adhesion and barrier properties.
• UV-Curable Inks and Coatings: Acts as a reactive oligomer or modifier in radiation-curable systems, contributing to film hardness and adhesion.
• Powder Coatings: Utilized as a functional additive or co-resin to improve flow, leveling, and intercoat adhesion in thermosetting powder formulations.
• Fiber-Reinforced Composites: Employed as a matrix resin or sizing agent to improve the interfacial adhesion between fibers (e.g., glass, carbon) and the polymer matrix.

Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Key parameters such as epoxy equivalent weight (EEW), acid value, molecular weight distribution, glass transition temperature (Tg), and viscosity are rigorously controlled. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
