Hydroxyethyl Methacrylate (HEMA)

Description

What is Hydroxyethyl Methacrylate (HEMA) ?

Hydroxyethyl Methacrylate (HEMA) is a clear, colorless liquid ester of methacrylic acid, widely used as a monomer in polymer and copolymer synthesis. With its hydroxyl functional group, HEMA provides excellent reactivity and compatibility, making it an essential raw material in the production of coatings, adhesives, contact lenses, resins, and biomedical applications. Its versatility, high purity, and strong adhesion properties have made it a critical intermediate in multiple industries.

Chemex Chemicals is a trusted supplier of high-quality Hydroxyethyl Methacrylate, catering to the global chemical industry with consistent quality and reliable supply.
