2-Hydroxyethyl Acrylate (2-HEA)

2-Hydroxyethyl Acrylate (2-HEA)

Category: Acrylic Monomer / Reactive Diluent / Specialty Chemical

Description

2-Hydroxyethyl Acrylate (2-HEA) is a clear, colorless, reactive monomer containing both hydroxyl and acrylate functional groups. It provides excellent adhesion, flexibility, and cross-linking ability when used in polymer and resin systems. 2-HEA enhances hydrophilicity, chemical resistance, and mechanical strength in coatings, adhesives, inks, sealants, and elastomers. The product is supplied stabilized to prevent polymerization during storage.

Applications

• UV-curable and radiation-curable coatings and inks
• Acrylic resins and copolymers
• Pressure-sensitive adhesives and sealants
• Textile and paper coatings
• Reactive diluent in epoxy and urethane systems
• Functional monomer for improving adhesion & flexibility
• Automotive coatings and industrial finishes
