Is 2-hydroxyethyl methacrylate soluble in water?
HEMA is an ester of methacrylic acid, soluble in water and has relatively low volatility. It copolymerizes easily with a variety of monomers, incorporates cross-link sites, imparts corrosion, fogging and abrasion resistance, and the hydroxyl group improves adhesion.
