Method for hot end coating of hollow glassware by deposition of metal compounds on the hot outer glass surface

Hot-end tempering of hollow glass bodies comprises applying a soln. of B-, Si-, Sn-, and opt. P-cpds. in water and/or organic solvents on the surface to be coated, and pyrolytically producing a layer of oxides of the elements, and opt. applying further layers on this layer in the process of hot and/...

More Information
Summary:Hot-end tempering of hollow glass bodies comprises applying a soln. of B-, Si-, Sn-, and opt. P-cpds. in water and/or organic solvents on the surface to be coated, and pyrolytically producing a layer of oxides of the elements, and opt. applying further layers on this layer in the process of hot and/or cold-end tempering. The first layer pref. has a thickness of 5-300 nm, and, on application of further layers, a total layer thickness of 10-300 nm is obtained. An agent for pyrolytically applying a metal oxide layer on hollow consists of: 4-35 (pts. wt.) of one or more Si cpds.; 1-27 B cpd(s); 8-43 Sn cpd(s).; 0-35 P cpd(s).; and 30-86 organic solvent (mixt.); and/or water.
