To promote adhesion between noble metal and glass substrate, we often
deposit 100-200A chrome as adhesion layer.

Hello everyone,

I am trying to coat some glass substrates with silver but the problem is
poor adhesion.  My coating thickness is approximately 200 nm.  Is there
any way I can pre-treat my glass surface with an adhesion promoter to
improve the quality so that silver can stick better?  Any suggestions
would be greatly appreciated.  Thanks a bunch,
