Silane compositions

摘要

There is provided a novel class of alkoxy silanes useful as corrosion inhibitors for metal surfaces and characterized by an alkylene group attached to silicon through a Si-C linkage. These compounds also contain nitrogen as an amine or an imine group in a linear or cyclic structure. Sulfur and/or a carbonyl or thiocarbonyl group may also be present. 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.
