Temperable low-e coating system; method for producing the same and a low-e glass product comprising said coating system

摘要

Low E-value layer system (10) comprises a lower diffusion layer (30) made from ZnSnO x, an antireflection layer (40) made from titanium oxynitride, an inner diffusion barrier layer (50) made from SnO 2 or ZnSnO x, a seed layer (60) made from ZnAlO x, a reflection layer (70) in the infrared region, a blocking layer (80) made from ZnAlO x and an upper layer (90) made from ZnSnO x arranged on a transparent substrate (20). The diffusion layer and the upper layer are made from zinc stannate containing tin in an amount of 48-52 wt.%. An independent claim is also included for a method for the production of a low E-value layer system.
