Zero is an efficient Glycerine anti-freeze, which we are marketing in small tins for use in motor cars. As, however, we understand your interest is in connection with aircraft engines, we are enclosing herewith our prices for bulk supplies. Invoices for the trial lots despatched to-day are being sent to you direct, which we trust is in accordance with your wishes. Enclosed with this letter are freezing and boiling curves, and a table of viscosities, which will no doubt prove of interest to you. Zero has no detrimental effect on metals, rubber joints, fabric etc. and can be used with complete safety in any type of internal combustion engine. We would like to add that it also has anti-fouling properties, and will completely prevent the formation of rust, lime deposits etc. in the cooling system. p.t.o. | ||
