What Kind of Coated Glass Can Be Tempered?

Jorma Vitkala

Lately, there has been a great deal of
discussion about what kind of coated glass can
be tempered. This is understandable because
there are many different types of coated glass on
the market, and new companies and coatings are
entering the market all the time. This has caused
confusion among glass processors as well as
customers.
Coating capacity, in large scale flat glass
producers and processors, has increased more in
the past two or three years than during the
previous 15 years. This rapid development
indicates that the coating industry believes there
is great potential in the architectural and
automotive industries. I personally believe that
within the next 10 years coated glass will be more
or less a standard product and clear glass will be
used only in special cases.
This paper will give you an idea of what kind
of coated glass can be tempered and the reasons
why some coatings cannot be tempered at all. It
will also give you some information about force
convection methods and about how force
convection helps us process these products.
