2-Hydroxyethyl Acrylate – High Purity Industrial & Lab Grade
Introduction
2-Hydroxyethyl Acrylate (2-HEA) is a highly versatile acrylate monomer widely used in coatings, adhesives, sealants, and resin modification. Known for its excellent reactivity, hydrophilic nature, and ability to improve flexibility in polymer systems, this compound has become a staple across industrial, laboratory, and research applications. At City Chemicals EU, we supply premium-grade 2-Hydroxyethyl Acrylate that meets strict international standards, ensuring reliability and consistency for our customers worldwide.
What is 2-Hydroxyethyl Acrylate?
2-HEA is a clear, colorless liquid with a mild odor, classified as a hydroxy-functional acrylate monomer. Its molecular structure combines acrylate functionality with a hydroxyl group, making it highly reactive in free-radical polymerization. This dual functionality allows it to act as both a crosslinking agent and a modifier, improving adhesion, flexibility, and weather resistance in end products.
How It Works
In polymer formulations, 2-HEA introduces hydroxyl groups that can react with isocyanates, melamine resins, or other curing agents. This creates strong covalent bonds, enhancing the durability and chemical resistance of the final product. When blended into coatings or adhesives, it increases water-wettability, ensuring superior adhesion on challenging surfaces such as metals, plastics, and glass.
Key Benefits
-
Enhanced Adhesion: Improves bonding strength on difficult substrates.
-
Flexibility & Toughness: Provides elasticity without compromising hardness.
-
Chemical Resistance: Withstands solvents, fuels, and environmental exposure.
-
Hydrophilic Properties: Ideal for coatings that require wettability and dispersion.
-
Versatility: Compatible with multiple resin systems (epoxy, urethane, polyester).
Safety & Handling
While widely used in industry, 2-Hydroxyethyl Acrylate requires careful handling. It is classified as an irritant and sensitizer, and prolonged exposure may cause skin or eye irritation. Proper personal protective equipment (PPE) such as gloves, goggles, and protective clothing should be used. Storage must be in a cool, ventilated environment, away from direct sunlight and sources of ignition.
Longevity & Shelf Life
When stored under recommended conditions, 2-HEA maintains stability and effectiveness for up to 12 months. The product should be kept in tightly sealed containers to prevent polymerization and degradation.
