Abstract

An aqueous solution of a mixture of silicon-organic compounds comprising: A. A silane of the general formula: ##STR1## wherein a is 1 or 2, b is 0, 1 or 2, and a +b is equal to or less than 3, p is 0 or 1, and R represents an alkylene moiety of 1 to 8 carbon atoms or arylene moiety, R' represents an alkyl moiety, X represents a hydrolizable moiety and Y represents a functional group or the CH.sub.3 or the CH.sub.2 .dbd.CH moiety, and B. A copolymer having the recurrent unit of the general formula: ##STR2## wherein R" represents OH and/or [O].sup.- [NH.sub.4 ].sup.+ and/or [O].sup.- [Me].sup.+ where Me is an alkali or alkaline earth metal and Z can represent a moiety of the formula: ##STR3## wherein R"' represents an alkyl moiety. Also disclosed are new copolymers having the recurrent unit ##STR4## wherein at least one of the Z moieties is a moiety having the formula ##STR5## wherein R"' represents an alkyl moiety. Also disclosed are the use of the aqueous solutions as coating agents for metals, inorganic oxidic and inorganic sulfidic materials. There is also disclosed the use of such aqueous solutions of silicon organic compounds as adhesivizing agents especially for securing inorg…
