PVD ion plating gold color on glassware is well known and used in the market, however, to improve the adhesion of coated film, the bonding layer is always applied before TiN/ZrN gold coating, which has an issue that from inside seeing through, it reflects the metal layer color: silver or dark silver.
If we use the Spraying paining + Aluminum metallization process do can generate a double-sides gold color result, but the adhesion is weak and more complicated process, it makes the labor cost and production cost is increased.
In Nov. 2020, we received the request from middle east customer: double-sides looks gold and not use the spraying painting process.
After several cycles experiments, we found the proper coating process with strong adhesion.
