Abstract:
An improvement in a process for the impregnation of masonry with an alcoholic or benzine solution of an alkyltrialkoxysilane or a partial condensation product thereof which improvement involves including in the alcoholic or benzine solution an organofunctional silane having a basic organo group or an alcoholate of an element selected from the group consisting of silicon, a metal of the First Main Group of the Periodic System, a metal of the Second Main Group of the Periodic System, a metal of the Fourth Sub-Group of the Periodic System, and a metal of the Fifth Sub-Group of the Periodic System; an improved composition for the impregnation of masonry comprising a mixture of an alkyltrialkoxysilane or a partial condensation product thereof and an organofunctional silane having a basic organo group or an alcoholate of an element selected from the group silicon, a metal of the First Main Group of the Periodic System, a metal of the Second Main Group, a metal of the Fourth Sub-Group of the Periodic System and a metal of the Fifth Sub-Group of the Periodic System.
Abstract:
A method for adhering an organic substance to a metallic or inorganic oxidic substance which comprises disposing between said organic substance and said metallic or inorganic oxidic substance a phosphorus organosilane of the general formula
WHEREIN EACH R is independently a substituted or unsubstituted aliphatic radical, each A is a bivalent alkylene or arylene radical or a bivalent oxyalkylene or oxyarylene radical joined by its oxygen to the phosphorus atom, m, n, p and x are each values of 0 or 1, B is either a bivalent oxygen radical, an -NHradical, an -NR- radical or an -S- radical when p is equal to 1 and y is equal to 1 to 20.
