hardening packing coating composition, method of coating a metal substrate with a hardening packing system, and foodstuff metal container. bisphenol a (bpa), bisphenol f, bisphenol α-diglycidyl ether (badge), and bisphenol f-diglycidyl ether (bfdge) free coat compositions for metal substrates including a subcoating composition containing a (co) ) polyester polymer, and an undercoat crosslinker; and an overcoating composition containing a poly (vinyl chloride) (co) polymer dispersed in a substantially non-aqueous carrier liquid, and an overcoating crosslinker, and a functional (meth) acrylic (co) polymer. Also provided is a method of coating a metal substrate using the bpa, bpf, badge and bfdge free coating system to produce a hardened protective coating useful in the manufacture of metal storage containers. The coated substrate is particularly useful in the manufacture of multi-part foodstuff storage containers with "easy-to-open" end closures. |
