VISION-LITE® / VISION-LITE II®

PROCESSING GUIDELINES

MAY 2022

16

Hereafter are some additional instructions:

• 

As VISION-LITE® II presents both faces with anti-reflective coating, the rollers and Kevlar® quality 
must be checked in detail.

• 

Tin side must be placed upwards and as a consequence air side will face rollers. Experience has 
shown that the sensitivity to overheating is more pronounced when air side is down – this allows 
more flexibility in the adjustment of the tempering recipe.

The tin side and the air side of the VISION-LITE® II can be identified on the cutting table by looking for 
the cutting line on the edge of the jumbo which is coming from the cutting wheel of the float line (air 
side). Tin check from BOHLE in calibrating mode could be used too (lower value = air side), advantage 
of the tool it that it could be used and works after grinding step and loose of face traceability. In case of 
need of support, contact your local TSM.

• 

At description in introduction of part 3, if the furnace is equipped with a glass detection sensor 
functioning by detecting the glass reflectance in order to signal the glass presence, this must be in 
certain situations used manually; in fact, the very low reflectance of the VISION-LITE® II glass may 
not be detected by the sensor and therefore it may not send the information to the equipment.

• 

Do not use SO

2

 in the furnace when tempering VISION-LITE® II. Do stop SO2 right in time. SO2 may 

remain in the furnace for up to 48h.

Heat-soaking toughened VISION-LITE® II cut sizes must be carried out in accordance with EN 14179 
European standard. Every piece must be individually separated; the separating blocks may be made out 
of PTFE (e.g. Teflon®) and contact with the coating should be limited to a minimum and located at the 
extreme edge of the glass. Gas fired heat-Soak-Test furnaces with direct combustion in the oven must 
not be used as hot fumes may damage the coating.

3.7. HEAT-SOAK TESTIN

VISION-LITE® II can be curved annealed (sagging process) or tempered (in tempering furnaces fitted 
with a bending cell). Not all curvature radius may be attainable with convex or concave shape according 
to the type of process used. The processor is then asked to check and validate that its bending process is 
capable to obtain a good quality on a particular shape before giving a final offer for a project requesting 
this shape.
SEMI VISION-LITE® (annealed version) cannot be curved.

3.8. BENDING
