What is 2-Hydroxyethyl Methacrylate CAS 868-77-9?

2-hydroxyethyl methacrylate (HEMA) is a multifunctional active monomer:

Wide application: Spanning three major fields including high-end coatings, medical materials, and the electronics industry, it is particularly irreplaceable in contact lenses and car paint.

High reactivity: It contains both vinyl and hydroxyl groups, and is easily involved in cross-linking and esterification reactions.

Operational sensitivity: It is necessary to strictly avoid light and refrigerate, and add polymerization inhibitors to prevent polymerization failure.

2-Hydroxyethyl Methacrylate CAS 868-77-9 Use

Synthesis of Polymer materials

Coating and resin modification: Copolymerize with acrylic monomers to form resins containing active hydroxyl groups, enhancing weather resistance and gloss (such as high-end car paint).

Medical materials: For manufacturing contact lenses and orthopedic fillers, due to its excellent biocompatibility.

Industrial additives

Adhesive: Used for textile adhesives and modification of non-woven fabrics.

Electronics and grease industry: dehydrating agents for electron microscopes, lubricating oil additives.

Functional monomer:

Uv-curing system: As a crosslinking monomer for radiation-cured coatings and inks.
