ABSTRACT:
Aluminum alloy finstock for making heat exchanger fins. The finstock is prelubricated with a water-microemulsifiable lubricant composition comprising an oil, an anionic surfactant, a polyalkoxy alkylphenol cosurfactant, and optionally a C.sub.10 -C.sub.36 mono- or dicarboxylic acid. The lubricant composition is preferably applied to the finstock dissolved in hexane which is then evaporated, leaving a water-microemulsifiable lubricant residue. The lubricated product is readily washable with water to microemulsify the lubricant residue into a microemulsion.
