Abstract
Abstract A laminate comprising an inorganic oxidic or metallic surface and a polymer, the laminate having in the region of the interface between inorganic oxidic or metallic surface and the polymer a silane having a capped function group; the use of silanes having capped functional groups as adhesivizing agents especially for use between organic polymers and substances having inorganic oxidic and/or metallic surfaces. Also disclosed is the surface of an inorganic oxidic or metallic surface resistive to corrosion by applying thereto a silane having a capped functional group.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
118 words
A process for protecting the surface of an inorganic oxidic or metallic surface against corrosion or for improving its adhesion to an organic polymeric material which comprises contacting said surface an aqueous solution of a silane having a capped functional group, said silane being one of those having the following formulas: ##STR4## wherein n = 1 to 8, a can be equal to 0 or 1, R represents oxygen or 2 hydrogen atoms, X represents oxygen or sulfur, and R' represents identical or different alkyl moieties which can be interrupted in the chain by an oxygen atom, the silane being applied in the form of a 0.05 to 5.0 weight percent solution and thereafter removing the aqueous solvent.
Claim 2
Dependent Claim
118 words
A process for protecting the surface of an inorganic oxidic or metallic surface against corrosion or for improving its adhesion to an organic polymeric material which comprises contacting said surface an aqueous solution of a silane having a capped functional group, said silane being one of those having the following formulas: ##STR4## wherein n = 1 to 8, a can be equal to 0 or 1, R represents oxygen or 2 hydrogen atoms, X represents oxygen or sulfur, and R' represents identical or different alkyl moieties which can be interrupted in the chain by an oxygen atom, the silane being applied in the form of a 0.05 to 5.0 weight percent solution and thereafter removing the aqueous solvent.
