Abstract

1508227 Lubricants MINNESOTA MINING & MFG CO 6 Oct 1975 [7 Oct 1974] 40826/75 Heading C5F [Also in Division G5] A wiping fabric for a magnetic disc contained in an envelope is impregnated with a lubricant comprising a highly fluorinated alkyl polyether having a viscosity index of 10-130; 1-20 parts by weight of the lubricant is provided per 100 parts by weight of the fabric. The fabric is impregnated by immersing it in a solution formed from 0À1 to 1À0 parts by weight of the lubricant in 100 parts by weight of a solvent and drying in air at room temperature.
