PROCESSING GUIDELINES

2.3. STORAGE
2.4. HANDLING
All glass products may degrade (become stained or corroded) when stored in humid conditions. The
iridescence may take the appearance of a “rainbow” or milky white haze on the surface of the glass, or
corrosion pitting on the coated side.
VISION-LITE® range glass sheets must be stored, as float glass, vertically (at 3 to 7 degrees) under the
following conditions:
•
In a dry, well ventilated warehouse, to prevent any condensation on the surface;
•
Away from glass dust;
•
Protected from rain and running water (e.g. any roof leakage must be rectified);
•
Never outside or in the open air (even when packed);
•
Protected from wide changes in temperature and humidity levels (coated glass products should be
stored far from opening doors).
•
In case the coated glass is delivered packed (aluminium, PE):
• Before breaking the seal, to avoid condensation, one should ensure that the temperature of the
pack has reached the temperature of the environment of the warehouse.
If the above (§ 2.3.1) storage conditions are respected, VISION-LITE® range is guaranteed for
2 years
from the date of reception
at the customer’s premises. In case the date of reception is lost by the
customer, the date of the delivery note will serve as evidence.
•
VISION-LITE® coated glass sheets must be handled with dry, clean and appropriate safety gloves.
•
In case handling operations with vacuum cups on the coated side cannot be avoided, make sure
that the vacuum cups are perfectly clean. Not all solutions are suitable for cleaning vacuum cups,
see manufacturer documentation for details. A sheet of interlayer paper (acidfree, thin, soft and
air-permeable) or suitable suction-cups caps can also be placed on the coated side, between the
vacuum cups and the surface, but care must be exercised as this may reduce the vacuum level
(especially in the case of thick and heavy panes).
•
Each coated glass pane must be released from the next pane before being lifted from the pack. Any
relative movement of the coating with the next glass pane must be avoided.
•
Automatic unstacking of glass sheets or removal using a glass clamp is possible, but the gripping
area should be kept to a minimum and condemned from the cutting pattern;
•
In case of doubt, the position of the coating must be checked (see § 1.5.2). Do not place the coating
in contact with a rough surface or hard objects.
•
Always avoid fingerprints and dirt traces which would require an additional cleaning of the coating.
If necessary, the coating may be gently wiped with a soft dry cloth and a suitable solution (e.g.
isopropyl alcohol (IPA)).
Scratches on the coating which occur during handling and processing, if the instructions of this guideline
are not respected, are visible when looked at from an incident angle (in reflectance). They are much
more visible than on the PLANICLEAR® clear glass. Wearing gloves is mandatory and all equipment
should be well maintained (without frictions on the coating layer).
