Description

2-Hydroxyethyl Methacrylate (2-HEMA) is an ester of Methacrylic Acid and is used as a raw material in the synthesis of polymers. 2-Hydroxyethyl Methacrylate (2-HEMA) can form homopolymers and copolymers. Its copolymers can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and other monomers.

Uses

Radiation-curable printing inks, wood/metal/plastic coatings, and electronic encapsulation.

Benefits

Enables balanced viscosity control and performance; supports high-gloss, scratch-resistant coatings.
