I’m sure you know the cost for CVD coatings are ~25% of the production costs for sputter coating and the benefits for hard coat increase when you consider failure from improper storage & handling of soft coat especially with guarantees on installed IG units manufactured with soft coat glass.
The history of the glass industry clearly supports advanced products gaining success. There will be more demand for coated products and SE can help you be a low cost producer of value added coated glasses. I welcome the opportunity to discuss CVD coating as your schedule permits. Please advise.
