Summary: | A coating composition comprising: a) a polyester imide polymer having an acid value of at least 25 mg KOH/g and a hydroxyl value of up to 5 mg KOH/g; and b) a crosslinker material operable to crosslink the acid functionality of the polyester imide polymer, wherein the coating composition is substantially free of bisphenol A (BRA), bisphenol F (BPF), bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE).
L'invention concerne une composition de revêtement comprenant : a) un polymère de polyester-imide ayant une valeur acide d'au moins 25 mg KOH/g et une valeur hydroxyle pouvant atteindre 5 mg KOH/g ; et b) un matériau de réticulation utilisable pour réticuler la fonctionnalité acide du polymère de polyester-imide, la composition de revêtement étant sensiblement exempte de bisphénol A (BRA), de bisphénol F (BPF), d'éther diglycidylique de bisphénol A (BADGE) et d'éther diglycidylique de bisphénol F (BFDGE). |
