ABSTRACT OF THE DISCLOSURE The invention provides isocyanatosilanes characterized by the presence of at least one free isocyanate group and containing a single silane grouping having the structure: Image said reactive isocyanate group being connected to said silane grouping through a divalent organic radical having at least one carbon atom, and wherein R is a divalent aliphatic, cycloalipha- tic or aromatic radical having from 1 to 20 carbon atoms; R1 is a monovalent aliphatic, cycloalphatic or aromatic radical having from 1 to 20 carbon atoms; R2 is a monovalent aliphatic, cycloaliphatic or aromatic organic radical having from 1 to 8 carbon atoms; and a is zero or 1. Compositions comprising at least one of said isocyanato silanes, preferably in combination with at least one polyisocyanate, and, optimally, at least one aromatic nitroso compound have been found to be unexpectedly effective as storage-stable, single-package, one-coat adhesive systems for bonding a variety of elastomeric materials to themselves and other solid substrates, such as metal, fabric, ceramic, and the like substrates.
