COATED ARTICLE WITH LOW-E COATING HAVING ZINC STANNATE BASED LAYER BETWEEN IR REFLECTING LAYERS FOR REDUCED MOTTLING AND CORRESPONDING METHOD

摘要

A coated article is provided which may be heat treated (e.g., thermally tempered) and/or heat bent in certain example instances. In certain example embodiments, a zinc stannate based layer is provided between a tin oxide based layer and a silicon nitride based layer, and this has been found to significantly reduce undesirable mottling damage upon heat treatment/bending. This results in significantly improved bendability of the coated article in applications such as vehicle windshields and the like.
