Tempered And Non-Tempered Glass Coatings Having Similar Optical Characteristics

摘要

Temperable and non-temperable coatings are provided which have similar optical characteristics. The non-temperable coating is placed on glass that is not to be tempered and provides certain optical characteristics. The temperable coating is placed on a glass substrate and the coated substrate is then tempered. After tempering, the coated tempered glass sheet and the coated non-tempered glass sheet have similar optical characteristics. Both coatings have a plurality of metal layers, with at least one of the metallic layers being a discontinuous layer with a primer layer over the discontinuous metal layer. For the non-temperable coating, the discontinuous metal layer has an effective thickness in the range of 1.5 nm to 1.7 nm. For the temperable coating, the discontinuous metal layer has an effective thickness in the range of 1.7 nm to 1.8 nm. The primer layer of the temperable coating is thinner than the primer layer of the non-temperable coating.
