Hydroxyethyl acrylate: Molecular Weight
Hydroxyethyl acrylate(abbreviated as HEA, chemical name: 2-Hydroxyethyl acrylate) has a molecular weight of 106.12 g/mol. It is a colorless liquid commonly used as a surfactant.
Hydroxyethyl acrylate can be simply described as a derivative of alkyl acetic acid, with the structural formula: CH₂=CH-COOC₂H₅. At room temperature, it exists in liquid form, with a boiling point of 202°C, a specific gravity of 0.87, a relative density of 1.001, and a refractive index of 1.4182. It exhibits excellent solubility: while it dissolves well in water, it can be easily separated from water at room temperature.

Hydroxyethyl Acrylate (HEA) stands out for its excellent miscibility with water and organic solvents, plus low viscosity—making it a seamless, efficient additive for coatings, inks, and adhesives.
