HEMA
2-hydroxyethyl methacrylate
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. It is also a key raw material for acrylic polyols.
