2-Ethylhexyl acrylate is an acrylic acid ester monomer commonly used to manufacture polymers for coatings and adhesives. It may also be used to lower the glass transition temperature (Tg) of acrylic polymers.
2-Ethylhexyl acrylate (2-EHA, CAS 103-11-7) is a building block for polymer manufacturing and a feedstock for chemical synthesis. It is available as a liquid packaged in drum quantities.
2-Ethylhexyl acrylate imparts excellent flexibility, great UV resistance, and high water resistance to polymers. It is commonly used to lower the Tg of polymers containing MMA, styrene, vinyl acetate, and other hard monomers.
2-Ethylhexyl acrylate is most frequently used to manufacture polymers for paints, coatings, and pressure-sensitive adhesives. It may also be used as a feedstock for chemical syntheses via addition reactions.
