There is provided a corrosion inhibiting alkoxy silane characterized by an alkyleneamino group attached to silicon through a Si--C linkage, a carbonyl or thiocarbonyl group attached to an amine group and a terminal group which may be saturated or unsaturated aliphatic or cycloaliphatic group containing 6 to 20 carbon atoms, a saturated or unsaturated aminoaliphatic or amino cycloaliphatic group containing 6-20 carbon atoms; NHNH.sub.2 ; NH(CH.sub.2).sub.n N(R).sub.2 ; or a ##STR1## group where R.sup.2 is a saturated or unsaturated alkyl or haloalkyl group containing 3 to 20 carbon atoms. The invention also provides a method of inhibiting corrosion of metal surfaces by applying a coating containing or consisting of a novel silane as above described.
