A clear, colorless liquid with a slight acrylic or fruity odor. It's comprised of a polymerizable methacrylate functional group on one end and a reactive ester group on the other end. It is slightly miscible with water, soluble in most organic solvents and has relatively low volatility. Its vapor is heavier than air. It copolymerizes readily with a wide variety of monomers. The added ester group imparts properties such as durability, strength, transparency and an elevated Tg.
