Abstract
This disclosure relates to use of a conversion coating for reduction or prevention of hydrogen sulfide production in cans holding hydrogen sulfide producing liquids, such as wine. This disclosure also relates to metal cans comprising a conversion coating layer deposited on at least a portion of the inside surface of the metal can, a film-forming layer deposited on such conversion coating layer, and a hydrogen sulfide producing liquid deposited inside the metal can.
Claims20
A metal can comprising:
- a conversion coating layer deposited on at least a portion of the inside surface of the metal can, wherein the conversion coating layer comprises a lanthanide series element, a Group VIB metal, a Group IIIB metal, a Group IVB metal, and/or a homopolymer or copolymer comprising a phosphorous-containing monomeric subunit m1 and optionally a non-phosphorous-containing monomeric subunit m2;
- a film-forming layer deposited on at least a portion of the conversion coating layer;
- and
- a hydrogen sulfide producing liquid deposited inside the metal can.
