Precoated steel sheet for two-piece can.

摘要

It comprises: a steel sheet; a precoating film formed on one surface of the steel sheet, which is to be the outer surface of a two-piece can, by applying a precoating composition onto the one surface of the steel sheet and curing same; and another precoating film formed on the other surface of the steel sheet, which is to be the inner surface of the two-piece can, by applying another precoating composition onto the other surface of the steel sheet and curing same. The above-mentioned precoating composition comprises a thermosetting coating material and an internal lubricant having a content ratio within the range of from 0.1 to 30 weight parts relative to 100 weight parts of a resin as a solid content in the thermosetting coating material. The above-mentioned another precoating composition comprises the above-mentioned thermosetting coating material and an aluminum powder having a content ratio within the range of from 10 to 400 weight parts relative to 100 weight parts of the resin as the solid content in the thermosetting material.
