Dear Sirs, We thank you for your letter (reference Rm{William Robotham - Chief Engineer}/AFM.{Anthony F. Martindale}2/MH{M. Huckerby}) of February 3rd, regarding Keenol Lubricants. Grade K.G.20 is made from a mineral oil lime soap base grease, and is quite suitable for chassis lubrication. It is a water resisting grease. Grade Z.9907 is made up largely of saponifiable oils and was developed specially for Press Tool Work and not for ordinary lubrication. Grade K.G.24 is made from a mineral oil soda base grease and is a high melting point lubricant. It is not suitable where water is present. Any further information required will be gladly forwarded upon request. Yours faithfully, for ALEXANDER DUCKHAM & CO. LTD., A.{Mr Adams} Hart. Keenol Sales. | ||
