VISION-LITE® / VISION-LITE II®
PROCESSING GUIDELINES

• Paper interlayer (chlorine free);
• Foam pads;
• Corrugated cardboard strips.
This is especially important with glass of different dimensions. Do not put additional separating powder.
The use of so-called “harp carts” to store the cut sizes is not recommended as the contact of the wires
on the coating may damage the latter when the cut sizes are pulled from or pushed in between the wires
•
In case such carts are however used: it must be ensured that the metallic wires are well protected
with plastic sleeves on their whole length. Those protections must be totally free of glass shards;
•
The cut sizes must be inserted in such a way that the coating is never rubbed onto the wires;
•
Such carts must not be used in case the coating is to be tempered.
For VISION-LITE® II only
(dual coating ‘to be tempered’ version):
•
In order to ensure the homogeneity after tempering, it is necessary to remove 20mm all around the
plate at the cutting step. The usable surface is therefore 40mm smaller than the full plate in both
directions: for instance, with 3210×6000 mm² PLF, the usable surface is 3170×5960 mm².
VISION-LITE® range does not need to be edge deleted whatever the configuration of use. It could be
used with polysulphide, polyurethane or silicone IGU sealants in respect of plant control plan.
It is good practice to edge work the glass directly after cutting. Provided the glass is stored under above
defined conditions, the glass must be edge worked within 5 days from cutting.
Edge-working machine must be thoroughly cleaned before working with VISION-LITE® range, especially
the parts coming into contact with the glass. The conveyor rollers must not slip on the glass (must not
be blocked). Water in the self-contained circuit of the edging machines must be regularly changed at
short intervals, in order to avoid charging the water with residual from edging.
•
Wet edge-working:
it is essential to keep the glass fully wet during the whole grinding process and to
wash the glass directly afterwards so that the grinding water is not able to dry on the coated surface.
•
Dry edge-working:
such processing is generally not recommended as small glass dust particles may
be sprayed on the dry coated surface. In case of use, make sure the suction is powerful enough to
avoid a too important dispersion of dust.
