and Expose Solution of Processing Laminated Glass With EVA
I have talked about the Bubbles
Solution for Laminated Class with EVA Film , and today I would
like to talk about the other problems you may face in
laminating glass with EVA FILM.
problems are: de-lamination
self-exposing of the laminated glass.
1) The heating temperature is
not high enough or the heatig time is not long enough for the EVA FILM
to melt and react totally, so the cross link reaction is not
For this reason, please
increase the heating temperature or prolong heating time of laminating.
2) The EVA FILM is out of the
shelf life, most EVA FILM's self life is about one year or
longer. Please use the EVA FILM within the self life. Yes,
different EVA FILM manufacturers may have different self life
for the EVA Film.
3)Maybe it's the problem of the quality of
the EVA FILM. Send
some film samples
to the EVA FILM
manufacturer to test the EVA FILM again.
4)The moisture of the glass or EVA FILM is
too much. EVA FILM are less sensitive to moisture, but if it's
too high, it will do harm to the adhesion of EVA FILM.
Please dry glasses
FILM in good
5)There is some organic substance on the surface of glasses. For example
oily substance will also do harm to the adhesion of EVA
Please clean the glasses if
necessary. You can use clean water, industrial alcohol, Acetone
to clean the glasses.
6) When laminated with the painting papers
(like PP, PVC), the printing ink is too much and not being
Please dry the printing papers
first before laminating with glasses and EVA FILM.
7) If you found the de-lamination is happening in the edges of the laminated
glass, here is why:
Maybe the workers'
the edges of the glasses, and there are oily substance in the
hand, which will do harm to the adhesion of the EVA
Please ask your worker to wear
Maybe its summer, and your
worker work very hard, and their hands are sweaty. And the
sweat will do harm to the EVA FILM.
1) The laminated glass is
cooling too fast. Please do not open the oven door to help
cooling after the temperature of the laminated glass is lower
than 75 degrees.
2) Please avoid the hot
laminated glass touching the cold water.
3) Put some wood blocks between
the laminated glasses to make the cooling is
4) The quality of the glass is
not good, which are easy to expose.
5) The EVA FILMs are not
eliminated the internal stress. Good quality EVA Film will be
eliminated the internal stress to make the EVA film less contracting.
If the EVA Film are not
eliminated the internal stress, then when laminating the glass
with EVA Film, the EVA Film's internal stress would try to
contract to its original state and expose the laminated
6.) The silicon bag is not clean, which means
maybe some block inside the silicon bag. So when the pre-
laminated glass on the block and vacuuming is working, the
pressure would break the laminated glass.
