The invention relates to a preservation / lubricant / primer-composition for metallic substrates, in particular for steel substrates such as strip steel, comprising at least one epoxidized oil. The composition can further contain at least one cross-linking component, such as an UV-initiator or a fatty polyacid. The epoxidized oil is preferably an epoxidized derivative of a natural unsaturated fat or oil, in particular an epoxidized derivative of a natural "drying oil". The composition can be used as a preservative, a lubricant and/or a primer for metallic substrates, in particular for storage/transportation, forming/(draw)processing, and/or applying a coating. The invention circumvents the use of separate compositions for each of these processing steps. L'invention a trait à une composition de conservation / lubrification / apprêt pour substrats métalliques, notamment pour substrats d'acier tels que de l'acier feuillard, qui comporte au moins une huile époxydisée. La composition peut contenir en outre au moins un constituant de réticulation, tel un initiateur d'UV ou un polyacide gras. L'huile époxydisée est de préférence un dérivé époxydisé d'une graisse ou d'une huile insaturée, notamment un dérivé époxydisé d'une </= huile siccative >/= naturelle. La composition peut être utilisée comme agent de conservation, lubrifiant et/ou apprêt pour substrats métalliques, notamment en vue d'un stockage/transport, d'un traitement de formage/étirage, et/ou d'une application de revêtement. Grâce à l'invention, il n'est plus nécessaire d'utiliser des compositions séparées pour chacune de ces étapes de traitement.
