Alternatives to Bisphenol A (BPA) based energy cure oligomers for printing and packaging applications

Dev Nagvekar, BASF Corporation

Abstract:Energy cure oligomers containing Bisphenol A (BPA) impart high chemical resistance, high reactivity and good surface hardness to inks and overprint varnishes (OPV) used in printing & packaging applications. In this paper, we will compare BPA-free and BPA-containing acrylates in flexographic ink and OPV and discuss performance differences between available options.
