What Is HEA 2-Hydroxyethyl acrylate CAS 818-61-1?

2-Hydroxyethyl Acrylate (HEA) is a clear, colorless liquid with a characteristic acrylate odor. It is a bifunctional monomer containing both acrylate and hydroxyl functional groups, allowing it to undergo polymerization and crosslinking reactions. This unique structure makes 2-hydroxyethyl acrylate a highly versatile raw material in coatings, adhesives, sealants, and polymer synthesis.

2-hydroxyethyl Acrylate Uses

1. Coatings and Paints

2-Hydroxyethyl Acrylate polymer is widely used in waterborne and solvent-based coatings to improve adhesion, hardness, and weather resistance. The hydroxyl group allows it to react with isocyanates, epoxies, and melamine resins, enhancing film performance and durability.

2. Adhesives and Sealants

HEA is a key component in reactive adhesives and sealants, providing excellent flexibility and bonding strength. Its reactive hydroxyl functionality ensures strong adhesion to metals, glass, plastics, and concrete surfaces.

3. Acrylic and Polyurethane Polymers

2-hydroxyethyl acrylate acts as a functional comonomer in polymer synthesis. It is often copolymerized with acrylates, methacrylates, and styrene to introduce hydrophilic and reactive sites into 2-hydroxyethyl acrylate polymer systems, improving compatibility and performance.

4. Textile and Leather Finishes

In textile and leather treatments, 2-hydroxyethyl acrylate enhances softness, durability, and resistance to wear, while maintaining breathability and surface strength.

5. UV and Radiation-Curable Resins

HEA is used as a reactive diluent and crosslinker in UV-curable coatings and inks, helping reduce viscosity and improve curing speed without sacrificing mechanical strength.
