Description
Butyl acrylate (CAS 141-32-2, EC 205-480-7) is an acrylic ester monomer commercially known under abbreviations including BA, TBA, and trade designations such as BA 100PPM and DL 325. It carries no assigned E-code. The molecular formula is C7H12O2 and it is classified under HS code 29161230.
In emulsion polymerisation, butyl acrylate acts as a soft-segment monomer that lowers the glass transition temperature of acrylic copolymers, directly influencing tack and flexibility in pressure-sensitive adhesives and architectural coatings. In food and fragrance applications, it functions as a flavorant and crosslinker at controlled concentrations to build specific ester profiles.
Butyl acrylate is supplied in inhibited grades (typically 100 ppm MEHQ) compliant with REACH registration requirements. FCC-grade material is available for flavour applications. Standard packaging includes IBC containers and bulk tankers, with documentation covering SDS, CoA, and REACH-compliant safety data.
