Description

2-Butenedioic Acid (2E)-, Dibutyl Ester, Polymer With Ethenylbenzene And 2-Hydroxyethyl 2-Methyl-2-Propenoate CAS NO 29297-14-1 is a specialized copolymer designed to deliver enhanced performance characteristics in advanced material formulations. This product matters because it combines the functional properties of fumarate, styrene, and hydroxyethyl methacrylate monomers, offering a unique balance of reactivity, compatibility, and film-forming ability. Industrial manufacturers in the coatings, adhesives, and specialty polymer sectors need this high-performance resin to develop products with superior durability, adhesion, and chemical resistance.

Application

• High-Performance Industrial Coatings: Used as a key resin component in solvent-based coatings for metal, plastic, and wood substrates, providing excellent gloss, hardness, and weatherability.
• Adhesives and Sealants: Serves as a polymeric binder in structural and pressure-sensitive adhesive formulations, enhancing tack, peel strength, and environmental resistance.
• UV-Curable Inks and Overprint Varnishes: Functions as a reactive oligomer or prepolymer that can be crosslinked under UV light, enabling fast-curing, low-VOC printing and finishing applications.
• Engineering Plastics and Composites: Acts as a modifier or compatibilizer in thermoplastic and thermoset composites to improve impact strength, fiber-matrix adhesion, and processing characteristics.
• Specialty Binders for Nonwovens and Textiles: Employed in formulations for fabric coatings and binders, imparting flexibility, water resistance, and durability to the finished material.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems. Every batch undergoes comprehensive analysis to ensure consistency in critical parameters such as molecular weight distribution, monomer content, viscosity, and acid value. Certificates of Analysis (COA) detailing these specifications are available upon request, providing full traceability and compliance data for your quality assurance protocols.

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. Due to its polymeric nature, prolonged exposure to elevated temperatures should be avoided to prevent changes in viscosity or molecular properties.
