2-Ethylhexyl Acrylate (CAS 103-11-7) is the ester of acrylic acid and racemic 2-ethylhexanol. Along with Butyl Acrylate it is the most commonly used acrylate in adhesives. It is often used to lower the Tg of an acrylic polymer.
2-EHA is a building block for polymer manufacturing and a feedstock for chemical synthesis. Polymers that incorporate 2-EHA have excellent flexibility, great UV resistance, and high water resistance. It is commonly used to lower the Tg of polymers containing MMA, Styrene, Vinyl Acetate, and other "hard" monomers.
