Description

2-Butenedioic Acid, Mono[2-[(2-Methyl-1-Oxy-2-Propenyl)Oxy]Ethyl]Ester is a specialized acrylate-functional monomer derived from maleic acid. This compound is valued for its ability to introduce reactive double bonds and carboxylic acid functionality into polymer chains, enabling cross-linking and property modification. It is primarily used by formulators and polymer chemists in the production of advanced coatings, adhesives, and specialty resins where enhanced adhesion, durability, and chemical resistance are required.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and cross-linking agent in formulations for wood, plastic, and metal coatings, contributing to fast curing and high gloss.
• Adhesives & Sealants: Imparts improved adhesion to difficult substrates and enhances the cohesive strength and chemical resistance of acrylic and polyurethane-based systems.
• Specialty Polymer Synthesis: Serves as a functional monomer for creating copolymers with tailored properties for dispersants, superplasticizers, and rheology modifiers.
• Dental & Medical Polymers: Used in the formulation of light-curable composites and restorative materials due to its biocompatibility and polymerization efficiency.
• Fiber Optic Coatings: Employed in coatings that protect optical fibers, providing essential environmental and mechanical protection.
• Photoresists & Electronic Materials: Acts as a component in photopolymerizable resins for microelectronics and printed circuit board manufacturing.
