DE-WATERING OF METAL SURFACES

A process of dewatering water-wet metal surfaces comprises coating the metal surfaces with a composition comprising an unstable emulsion in water of a non-volatile oil, e.g. hydrocarbon oils as spindle oil, containing an oil soluble surface active p agent, e.g. a non-ionic condensate of ethylene oxi...

Beschreibung
Zusammenfassung:	A process of dewatering water-wet metal surfaces comprises coating the metal surfaces with a composition comprising an unstable emulsion in water of a non-volatile oil, e.g. hydrocarbon oils as spindle oil, containing an oil soluble surface active p agent, e.g. a non-ionic condensate of ethylene oxide, with a material containing fatty hydrocarbon chains. The surface active agent comprises from 1 to 10% by weight of the oil, and the composition comprises from 0.5 to 10% by weight of oil. A corrosion inhibitor may be contained in the oil.
