Butyl acrylate is a low Tg acrylic monomer that is used to produce flexible acrylic polymers and copolymers used in adhesives, caulks, and sealants.
Butyl Acrylate (CAS 141-32-2) 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 butyl acrylate into a polymer helps to improve tack, flexibility, impact resistance, and overall durability. The flexibility and tack provided by butyl acrylate make it an ideal monomer for producing polymers used in adhesive and sealant applications.
