Process for producing surface-sealed hollow glass containers having a high use strength

摘要

A process for producing surface-sealed hollow glass containers, the hollow glass containers are, in the production process in the region of the exit from the annealing lehr which is located downstream of a machine for producing hollow glass containers, coated by means of a water-based cold end coating composition comprising at least the following components:I. a trialkoxysilane, a dialkoxysilane and/or a tetralkoxysilane or their hydrolysis and/or condensation products and alsoII. a water-soluble or water-dispersible mixture of a polyol and a crosslinker,wherein the applied layer of the cold end coating composition is subsequently subjected to a crosslinking step. The hollow glass containers produced in this way have an improved strength.
