PROCESS FOR MANUFACTURING SURFACE-SEALED HOLLOW GLASS CONTAINERS

摘要

PURPOSE: A manufacturing method for a surface sealed hollow glass container is provided to use a cold end coating composition. CONSTITUTION: A process for manufacturing surface-sealed hollow glass containers is characterized in that during the manufacturing process the hollow glass containers are coated with a water-based, cold treatment product at the outlet area of the cooling furnace arranged after a machine for manufacturing hollow glass containers. The water-based cold treatment product contains the following components:(I) a water-based organopolysiloxane-containing composition produced from alkoxysilanes bearing a functional group and alkoxysilanes selected among trialkoxysilanes, dialkoxysilanes and tetra-alkoxysilanes; and (II) a silicium-free component selected among waxes, partial fatty acid esters, fatty acids and/or surfactants. The thus produced hollow glass containers have an increased continued use resistance.
