Description

Butyl Hydroxyethyl Fumarate is a high-purity specialty ester derived from fumaric acid, valued for its reactive double bond and terminal hydroxyl functionality. This unique bifunctional structure makes it a versatile intermediate for synthesizing advanced polymers, coatings, and performance additives. It is essential for manufacturers in the polymer, specialty chemical, and advanced materials sectors seeking to enhance product durability and cross-linking efficiency.

Application

• Polymer & Resin Modification: Acts as a reactive diluent and cross-linking agent in unsaturated polyester resins (UPR) and vinyl ester resins.
• UV-Curable Coatings & Inks: Serves as a key monomer in formulations for fast-curing, high-performance surface coatings and printing inks.
• Adhesive Formulations: Used to improve adhesion strength and flexibility in structural and pressure-sensitive adhesive systems.
• Specialty Plasticizers: Employed in the synthesis of polymeric plasticizers for PVC and other polymers requiring low migration and high permanence.
• Biomedical Materials: Investigated as a building block for biodegradable and biocompatible polymers in controlled-release applications.
• Composite Materials: Enhances the interfacial bonding and mechanical properties in fiber-reinforced composites.
