2-Hydroxyethyl methacrylate (HEMA)

Hydroxyethyl methacrylate (HEMA). It is a clear, colourless liquid with a characteristic odour. It is an ester of methacrylic acid. It easily dissolves in water, relatively low volatility, non-toxic and non-yellowing.

HEMA copolymerizes readily with a wide variety of monomers, and the added hydroxyl groups improve adhesion to surfaces, incorporate cross-linking sites, and impart corrosion, fogging, and abrasion resistance, as well as contribute to low odour, colour, and volatility.

HEMA is used in the manufacture of acrylic polymers for adhesives, printing inks, coatings and metal applications. HEMA is also widely used as reactive diluent and alternative to styrene in unsatured polyester (UPR).

Shelf Life

Under proper storage conditions, the shelf life is 12 months.
