Description

2-Butenedioic Acid (2E)-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Propenoic Acid CAS NO 26007-18-1 is a high-performance, multi-component polymer resin designed for demanding industrial applications. This specialized copolymer combines the functional properties of fumaric acid with the structural versatility of butadiene, styrene, and acrylic acid monomers. It is essential for formulators seeking to enhance the durability, adhesion, and chemical resistance of their products. Key industries that rely on this advanced material include coatings, adhesives, and construction chemicals.

Application

• Industrial and Protective Coatings: Used as a key resin binder to improve film hardness, weatherability, and corrosion resistance in metal primers and topcoats.
• Construction Adhesives and Sealants: Imparts excellent adhesion to diverse substrates (concrete, metal, plastics) and enhances flexibility in tile adhesives and construction sealants.
• Textile and Paper Coatings: Serves as a functional polymer for coatings that require water resistance, stiffness, or specific surface properties.
• Composite Materials: Acts as a matrix resin or modifier in fiber-reinforced plastics and other composite systems to improve mechanical strength.
• Printing Inks: Utilized in formulations for improved pigment wetting, gloss, and adhesion on non-porous surfaces.
• Automotive Underbody Coatings: Provides stone-chip resistance and protection against road salts and moisture.
