Abstract

1,203,855. Protective coatings for boilers and heat exchangers. S. HUTTER K.G. 5 March, 1969 [5 March, 1968], No. 11672/69. Headings B2E, B1V and B1X. 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.
