Butyl acrylate (CAS 141-32-2) is the ester of n-butanol and acrylic acid. It is typically be used to lower the Tg of polymers used in coatings, inks, adhesives, caulks, and sealants
Butyl Acrylate (BA) is a low Tg monomer that can be easily polymerized with high Tg monomers like MMA, Styrene, and Vinyl Acetate in order to balance the properties of the final polymer. Incorporating BA into a polymer helps to improve tack, flexibility, impact resistance, and overall durability.
