The advancement of material science and polymer chemistry relies heavily on the availability and understanding of key monomers. 2-Hydroxyethyl Acrylate (HEA), known by its CAS number 818-61-1 and formula C5H8O3, is a prime example of such a critical component. Its distinctive chemical structure, featuring both an acrylate functional group and a hydroxyl group, provides a unique combination of properties that are invaluable for creating high-performance polymers. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of HEA, is committed to supporting innovation by providing this essential monomer.

The core advantage of HEA lies in its bifunctionality. The acrylate moiety enables HEA to readily copolymerize with a wide range of other vinyl monomers through radical polymerization. This allows formulators to precisely tailor the properties of the resulting polymers. Simultaneously, the hydroxyl group offers a versatile handle for post-polymerization modification or for influencing the polymer's interaction with its environment.

Key Properties and How They Benefit Formulations:

  • Enhanced Adhesion: The polar hydroxyl group promotes strong interactions with various surfaces, significantly improving the adhesion of polymers in coatings and adhesives. This is crucial for applications requiring long-term durability.
  • Improved Flexibility and Impact Resistance: Incorporation of HEA into polymer chains can increase flexibility and toughness, preventing brittle failure and improving impact resistance.
  • Hydrophilicity and Water Absorption: The hydroxyl group imparts hydrophilicity, making HEA useful for polymers designed to interact with water, such as in certain coatings, emulsions, or hydrogels.
  • Crosslinking Capabilities: The hydroxyl group can readily react with crosslinking agents like isocyanates, epoxies, or melamines. This crosslinking enhances the polymer's mechanical strength, thermal stability, and chemical resistance.
  • Reactive Diluent: In radiation-curable formulations (UV/EB), HEA can act as a reactive diluent, reducing viscosity and increasing the speed of polymerization upon exposure to radiation.

Industrial Impact of HEA:

The versatility of HEA makes it a sought-after monomer for numerous industries. As a manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. sees significant demand for HEA in:

  • Coatings: From automotive finishes to industrial protective coatings, HEA contributes to superior adhesion, flexibility, and weatherability.
  • Adhesives: It enhances the tack, peel strength, and cohesive strength of various adhesive systems, including pressure-sensitive adhesives.
  • Elastomers and Synthetic Rubber: HEA serves as a modifier, improving the thermal and mechanical properties of synthetic rubbers.
  • Paper & Textiles: Used to impart water resistance and strength in paper coatings, and to improve finishing in textiles.
