Description

Diethyleneglycolmaleate is a versatile bifunctional monomer and chemical intermediate. This compound is valued for its ability to introduce both unsaturation and hydroxyl functionality into polymer chains, enabling cross-linking and modification of material properties. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product performance through tailored molecular design.

Application

• Unsaturated Polyester Resins (UPR): A key monomer for producing resins used in fiberglass-reinforced plastics (FRP), gel coats, and cultured marble.
• Radiation-Curable Coatings & Inks: Serves as a reactive diluent and cross-linker in UV/EB-curable formulations for wood, plastic, and metal substrates.
• Alkyd Resin Modification: Used to introduce air-drying properties and improve drying times, flexibility, and chemical resistance in surface coatings.
• Adhesives & Sealants: Imparts enhanced adhesion, cohesion, and environmental resistance in structural and industrial adhesive systems.
• Specialty Polymer Synthesis: Acts as a building block for synthesizing copolymers with specific functionalities for advanced material applications.
• Chemical Intermediate: Utilized in organic synthesis for producing derivatives used in pharmaceuticals, agrochemicals, and other fine chemicals.
