818-61-1
Product name: 2-Hydroxyethyl Acrylate
English alias: HEA; Hydroxyethyl acrylate; Acrylic acid 2-hydroxyethyl ester
CAS: 818-61-1
Molecular formula: C5H8O3
Appearance: Colorless to light yellow transparent liquid
Package: 25kg/drum
2-Hydroxyethyl Acrylate (HEA) is a functional monomer containing both a reactive acrylate group and a hydroxyl group. It is widely used in polymer synthesis due to its ability to form strong cross-linked networks through free radical polymerization. HEA contributes excellent adhesion, weather resistance, and flexibility to coatings and adhesives.
Its hydroxyl functionality allows it to react with isocyanates and other crosslinkers, making it a valuable intermediate in the production of UV-curable resins, polyurethane dispersions, and other performance polymers. It is also miscible with water and many organic solvents, making it easy to handle and blend in formulation systems.
The chemical formula of 2-Hydroxyethyl Acrylate is C5H8O3, and it typically appears as a colorless to slightly yellow transparent liquid with a mild ester-like odor.
