ABSTRACT:
Dry prelubricating composition for steel substrates to be fabricated comprising a polyhydric alcohol-carboxylic acid lubricant derived from a saturated ester, a partially esterified vegetable oil plasticizer, an aromatic polyether surfactant and preferably, in addition, an ethylenic polymeric film strengthener and hindered phenolic antioxidant. The composition is to be transformed to the liquid state by rendering it molten or dissolving it, then applied to the substrate (hot) and subsequently cooled to provide a prelubricating film which is removable by treatment with an alkaline solution.
