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 also
II. 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.
一种生产表面密封中空玻璃容器的方法,该方法中空玻璃容器,在生产过程中,位于制造中空玻璃容器的机器下游的退火炉出口区域,通过使用水基冷端涂层组合物进行涂层,该组合物包括至少以下组分:I. 三烷氧基硅烷、二烷氧基硅烷和/或四烷氧基硅烷或其水解和/或缩合产物;以及II. 一种水溶性或水分散性的聚醇和交联剂混合物,其中,应用的冷端涂层组合物层随后经过交联步骤。以这种方式生产的中空玻璃容器具有更好的强度。
