Abstract

The invention relates to a new primer for pretreating glass in readiness for waterproof bonding to other substrates. The primer contains resins, functional silanes, solvents, and organosilazanes and, if desired, polyfunctional isocyanates and other additives. Compared with conventional primers, the resistance of the bond to hydrolysis is significantly improved.
