2-Hydroxyethyl Acrylate (2-HEA)

Hydroxyethyl Acrylate (2-HEA)
CAS#: 818-61-1
Synonyms: Hydroxyethyl acrylate, 2-HEA

Hydroxyethyl Acrylate (2-HEA) is a clear, colorless liquid with a mild odor, widely used as a reactive, hydroxyl-functional acrylate monomer. Its hydroxyl group enables cross-linking with isocyanates, melamines, epoxies, and other functional resins, enhancing polymer performance. 2-HEA provides excellent adhesion, flexibility, and chemical resistance, making it valuable in high-performance resin systems.

Key Features:

• Provides hydroxyl functionality for cross-linking

• Enhances adhesion to difficult substrates

• Improves chemical, solvent, and abrasion resistance

• Contributes to flexibility and toughness in polymer films

• High reactivity and compatibility with acrylic monomers

• Useful for waterborne, solventborne, and UV-curable systems

Applications:

• High-performance coatings (industrial, automotive, wood)

• Adhesives and sealants

• UV/EB-curable resins

• Thermosetting acrylics and polyurethane dispersions

• Printing inks and specialty polymers
