Description

Butyl 2-Hydroxymethylethyl Maleate is a specialty ester monomer derived from maleic acid and butyl glycol. This compound is valued for its bifunctional nature, offering both a polymerizable double bond and a reactive hydroxyl group, making it a versatile intermediate for controlled polymerization and cross-linking reactions. It is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries for synthesizing high-performance resins, adhesives, and surface modifiers.

Application

• Polymer & Resin Modification: Acts as a reactive diluent and cross-linking agent in the production of unsaturated polyester resins (UPR) and alkyd resins.
• Coatings & Inks: Used to enhance flexibility, adhesion, and curing properties in industrial coatings, UV-curable inks, and radiation-curable formulations.
• Adhesive Formulations: Serves as a key monomer for improving tack and cohesive strength in pressure-sensitive and structural adhesives.
• Specialty Monomers: A valuable intermediate for the synthesis of more complex monomers and oligomers with tailored properties.
• Plasticizers & Additives: Can be utilized in the development of polymeric plasticizers and performance additives for PVC and other polymers.
