CVD Online Coating

What is CVD?
Chemical Vapor Deposition (CVD) is an on-line pyrolytic coating technology integrated directly into the float glass manufacturing process. A variety of techniques are available to deposit thin films on flat glass. The most widely used for producing high quality functional coatings can be subdivided into two classes:

  1. physical vapour deposition (PVD)
  2. chemical vapour deposition (CVD).

PVD processes include several options, sputtering being most widely used for glass. Sputtered coatings are generally referred to as soft coated. Pyrolytic coatings are applied using CVD methods and are often referred to as hard coated. Both types of coating offer their own advantages and disadvantages.

The advantages of CVD include a high deposition rate and high degree of control. Tuning the process is simply a matter of manipulating the vapor flows in the coating zone. And, because the coating is bonded to the glass surface, the result is a glass coating with unparalleled durability.

Depending on the desired end product, one or several coatings can be applied. Coatings can be applied inside the tin bath, at the lehr entry or both.
