Hydroxyethyl Methacrylate, commonly referred to as HEMA, is a functional acrylic monomer characterized by its dual reactivity through both a polymerizable vinyl group and a reactive primary hydroxyl group. This versatile liquid chemical functions as a high-performance crosslinking agent and adhesion promoter, facilitating the production of thermosetting acrylic resins and automotive topcoats that require superior chemical resistance and gloss retention. In industrial adhesive formulations and the manufacture of hydrophilic polymer matrices, it is utilized to enhance substrate wetting and provide moisture-regulating properties in specialized coating systems. We provide this material with competitive factory pricing, supporting requirements for customized specifications to meet specific inhibitor levels and low-acid value standards. All shipments are accompanied by comprehensive MSDS, TDS, COA documentation to ensure full regulatory compliance and are available for bulk supply to support continuous high-capacity industrial production.

FAQ - Technical & Supply Chain
-
Q:
How is the polymer stability of Hydroxyethyl Methacrylate managed during long-term industrial storage?
A: The technical identity is verified under CAS 868-77-9, and the monomer is typically stabilized with specific inhibitors like MEHQ to prevent premature polymerization, ensuring consistent shelf life and reaction kinetics in industrial batches. -
Q:
Is Hydroxyethyl Methacrylate suitable for the production of UV-curable industrial coatings?
A: Yes, this material is commonly applied as a reactive diluent and functional monomer in radiation-curable systems to improve toughness and inter-coat adhesion, intended for professional industrial coating manufacturing rather than general consumer use.
