Abstract

A mixture of a bitumen/water emulsion and an alkali is applied to metal surfaces e.g. of boilers and heat exchangers to form a protective coating against the effects of smoke or exhaust gases. The mixture preferably comprises a 50:50 bitumen/water emulsion mixed with an equal amount of a 10% aqueous solution of Na 3 PO 4 . Up to 30% wt of graphite may also be added.
