Hydroxyethyl Acrylate: Essential Chemical Properties

Hydroxyethyl acrylate (HEA) represents a critical monomer in specialty chemical formulations with molecular formula C₅H₈O₃. This bifunctional compound combines vinyl reactivity with hydroxyl functionality, enabling dual reaction mechanisms during polymerization. The presence of β-hydroxyl ester groups (log P value of 0.32) enhances water solubility while maintaining compatibility with organic matrices.

Technical specifications typically include:

• Molecular weight: 116.12 g/mol
• Boiling point: 205-210°C at 760 mmHg
• Viscosity: 5-7 mPa·s at 25°C
• Refractive index: 1.450-1.455

Storage requires temperature-controlled environments (15-25°C) with hydroquinone inhibitors (200±50 ppm) to prevent spontaneous polymerization. Recent analytical studies by the Polymer Research Consortium show HEA maintains 98.7% purity after 12-month storage under nitrogen atmospheres.

Industrial Applications Analysis

The multifunctionality of hydroxyethyl methyl acrylate derivatives enables diverse implementations across sectors. Approximately 75% of global HEA production is consumed by adhesive formulators developing pressure-sensitive tapes and structural bonding agents. Automotive OEMs increasingly utilize these compounds in ultraviolet-curable coatings, reducing curing times from 8 hours to 45 seconds.

Additional applications include:

• Dental composites with 18% improved flexural strength
