 At each stage of the processing procedure, the personnel responsible for handling the glass
must have the adequate equipment: safety shoes, safety gloves, safety glasses.
 Product shelf life with protection (closed packaging): the glass has to be consumed within 9
months from the delivery in the processor’s facility.
 The Stopray SMART range is self-matchable, except for Stopray SMART 32T: these
products can be used annealed or heat treated as required by the application. Both
annealed and heat treated products have similar reflection and transmission characteristics.
In case of heat treatment, the procedure and set up of the furnace in chapter 6 of this manual
must be strictly respected.
 Stopray SMART Coatings, when installed in insulating glazing units, have to be assembled
with the coating towards the cavity so in position 2 of the insulating glazing. The glass should
be assembled in insulating glazing within one week after being heat treated, but advisable
to be assembled earlier.
 Stopray SMART 51/33, which can be laminated with coating against PVB, should be
installed in Position 2 so that coating layer is embedded within the laminated glazing and
thereby protected. For more information, refer to Section 9. (*depends on the durability test,
this paragraph might be removed if the test des not passed)
 We advise processing and handling this coated glass with care in order to avoid coating
damage. The personnel responsible for handling must wear clean gloves to ensure that
no fingerprints are left on the glass. Therefore we strongly recommend that everything
coming into contact with the coating of the glass during preliminary processes be pre-
validated.
 No edge deletion: Tests using different sealants have shown that, under strict conditions and
with a selection of sealants, prior edge-deletion is no longer required.
 Edge deletion is required for laminating SMART 51/33. For more information, refer to
Section 9.
 For the various glazing methods (traditional framing, structural glazing) tests for compatibility
and adherence of the coating with the sealant must be made in each case with the
sealant manufacturer.

1. PRODUCTS
This Processing Guide concerns the Stopray SMART products: Stopray SMART 51/33, Stopray
SMART 30/20 and Stopray SMART 32T.
The Stopray SMART products can be used either annealed (so without heat
treatment) or with heat
treatment (thermal toughening or heat strengthening).
The Stopray SMART products can be used in this configuration:
I. RECEPTION AND STORAGE
1. Unloading
The packs of glass must be inspected on arrival. AGC shall accept no liability for coating defects arising
after delivery or during handling, processing or installation of the finished product in the building if this
procedure is not followed:
 The rack must be positioned on perfectly level ground.
 Use the appropriate handling equipment.
 The grab must be perfectly centered.
 Avoid damaging the protective packaging whilst handling.
 The glass must be stored on appropriate racks.
 All recommendations given in this Processing Guide shall be strictly followed.
General comments:
 Clamps, slings, lifting beams and other handling equipment must comply with prevailing regulations
and be approved by the relevant authorities.
 Ensure the safety of personnel at all times. Keep all unnecessary personnel out of the handling
area. Wear appropriate personal protective equipment.
 Personnel must have received the required training.
Due to the fact that the interlayer powder is removed during the washing process, we recommend
placing micro-suction pads around the edge of each sheet of glass in order to prevent contact between
the glass and the coatings. Paper with a neutral pH can also be used, for example, for large pieces.
The personnel responsible for handling the glass must wear clean gloves suitable for handling coated
glass.

2. Storage of the packs
Storing packs correctly reduces the risk of chemical or mechanical damage to the glass.
As a general rule, care should be taken to avoid major fluctuations in temperature and humidity that may
cause condensation on the glass. Such fluctuations generally occur near loading and unloading areas.
No water must be allowed to come into contact with the sheets of glass.
Care should be taken to ensure that the ambient air is not polluted by any corrosive elements such as
chlorine or sulphur. Sources of such elements include machinery fitted with heat engines, battery-
charging points, road salt on the ground and so forth.
Factory racks are used for packaging during transport and are not designed to be used for storage.
Consequently, the coated glass must be stored on racks with spacers between packs ensuring that all
packs of the same size are stored together.
Stock sheets
Special packaging requirements apply in function of the final destination of the coated glass packs.
Shelf life: the glass has to be consumed within 9 months from the delivery to the customer’s port.
When protection is needed, desiccant bags are fit on the upper side and on the lateral sides of the stack
(two thirds of the height, from the upper corners).
Once the protective packaging is opened, the remaining sheets cannot be re-packed.
Upon receipt, we advise you to check if the packaging has been damaged during transport/handling. If
the weather-proof packaging has been damaged, condensation marks may appear on the glass. In this
case, you should open the packaging to take out a desiccant pack and weigh it. Contact AGC
immediately.
However, it is important to bear in mind a number of additional points:
 The sheets must be moved using a suction-pad lifting beam or an automatic unstacking machine. The
suction pads are placed on the glass side.
 If the glass is handled by placing suction pads on the coating, these suction pads must be perfectly
clean and covered with a protective material.
 Care must be taken to ensure that the suction pads/coating do not slip.
 The personnel responsible for unloading must wear clean gloves to ensure that no fingerprints are left
on the glass.
General comments:
If, despite the precautions taken, marks do appear on the coating (fingerprints etc.) they should be
removed at once using a clean, soft and wet (water) cloth and then a dry cloth. Soft circular movement
should be applied.

2. Cutting
The following specific precautions must be taken when cutting:
 When cutting, the coated side must be facing upwards to avoid any contact between the coated
side and the surface of the table.
 The cutting oil used should be compatible with the coating, sufficiently volatile and water soluble.
 The table and any break-out equipment coming in contact with the coating on the glass must be
pre-validated.
 Cutting personnel must wear clean gloves to avoid leaving finger marks on the coating.
 If the glass is to be cut using a template, the template must be positioned very carefully and care
must be taken not to scratch the coating. We recommend placing a protective sheet between the
template and the glass.
 The cut sheets of glass must be stored on racks. Care must be taken when handling them to ensure
that the coating on the first sheet does not rest against the back of the rack. All subsequent sheets
should be turned the other way.
 No particular spacer is needed if the original interlayer powder is still present. However, if for any
reason there is not enough interlayer powder left on the glass, we recommend that you place cork
spacers between the sheets.
 The coating around the edge of the glass may be removed during the cutting process provided that
dust from grinding is properly removed.
 For ease of detecting if a Stopray SMART is present in a laminated safety glass during the
processing:
> before cutting:
Check on the presence of coating deposition on the edge (a reflection means: coated glass).
> after cutting:
Put a sticker on the uncoated glass side of cut-sizes before unloading from the cutting table.
If during the processing the sticker gets lost: compare the edge of the cut-size, the glass component
with a darker edge appearance is the coated glass.
3. Edge-processing
The Stopray SMART 51, 30 and 32T products are designed to possibly undergo thermal toughening or
heat strengthening. Accordingly, edge processing is required.
3.1 Handling the glass
The personnel responsible for handling and shaping the edges of the glass must wear perfectly clean
safety gloves.
3.2 Shaping the edges
Several types of edging machinery are available on the market:
3.2.1. Crossed belt system
We recommend for personnel to work with diamond belts and adhere strictly to the supplier’s
instructions, specifically in terms of speed and cooling. For thicknesses in excess of 6 mm, we
recommend 'smooth edge' shaping.
3.2.2. Vertical single edging system
Since the glass is held with chain tracks and, depending on cleanliness and maintenance of the
machine, there is a risk of scratching the coating.

8
AGC Stopray SMART –Processing Guide –Version 4.1 –May 2020
3.2.3. Horizontal double edging system
It is possible to use this type of machine provided that the glass is held by smooth, non-textured belts.
The speeds of the various belts must be synchronised. Mains water jets are placed in such a way
that the coating is soaked and cleared of various impurities (e.g. separating powder or glass dust)
just before they come into contact with the upper roller belts.
3.2.4. Numerical Control Systems (CNC)
Shaping using a numerically controlled machine is permitted provided that the glass is placed with
the coated side facing upwards.
General recommendations for shaping edges:
 The glass must remain moist throughout the shaping process in order to prevent 'natural drying'.
 The glass must be washed as soon as it has been shaped.
 The glass may be drilled provided that the press is covered with a soft protective material.
 The glass may be processed using dry crossed belts provided that the extraction system is
sufficiently effective to remove the dust resulting from grinding.
3.3 Unloading
Due to the fact that the interlayer powder is removed during the washing process, we recommend placing
micro-suction pads around the edge of each sheet of glass in order to prevent contact between the glass
and the coatings. Paper with a neutral pH can also be sued, for example, for large pieces.
The personnel responsible for handling the glass must wear clean gloves suitable for handling coated
glass.
4 Edge Deletion
Tests using different sealants have shown that, under strict conditions and with a selection of sealant,
prior edge-deletion is no longer required. A specific brochure “ SEALANT COMPATABILITY – Technical
information for Stopray SMART products” available on www.agc-tas.com describes these conditions.
Contact AGC Technical Advisory Service for further information ( [email protected] ). The described
instructions must be strictly respected and executed.
5 Washing
This stage involves washing, rinsing and drying the glass.
A main-water spray station should be installed just before the point where the glass enters the
washer. This will remove any abrasive elements on the coating (cutting and edge-processing
residues) that could cause scratches when the brushes make contact with the coating.
The glass must be washed in clean, deionized water with a pH of 7 (± 1) and a conductivity of
< 30µS/cm. No hard particles (such as calcium) or acidic/detergent agents should be present in the
water used for washing and rinsing as these may damage the coating.
We recommend the use of 'soft' brushes (diameter of the bristles <0.15 mm), 1-2 mm of which come into
contact with the glass. There must be enough water to guarantee that the water is distributed evenly and
efficiently across the coating before it comes into contact with the brushes. It is also important not to stop
the cycle whilst the glass is in the washing machine.
After washing, micro-suction pads should be used on the perimeter of the glass in the area that

9
AGC Stopray SMART –Processing Guide –Version 4.1 –May 2020
normally would be edge-stripped in order to avoid any contact between glass and coating. For large
sheets of glass, a sheet of paper should be placed on the center of the glass.
The glass must be completely dry. We recommend checking whether the air filters of the ventilation
units are clean.
Two or three halogen lights should be present at the exit of the washer to light the glass
correctly (vertically from top to bottom) and even detect and quickly correct any deviations from
the requirements listed above.

6 Silk screen printing
6.1 Stopray SMART with silkscreen
In case of a silkscreen on the Stopray SMART, where the silkscreen is in contact with the sealant joint, the
edge-deletion of the coating is required prior to the application of the silkscreen.
For silkscreen that is in contact with the sealant joint, the compatibility of the sealant joint, structural
joints and weatherseals with the silkscreen (enamel) paint is under responsibility of the manufacturer of
the insulating glazing units, and should be assessed in cooperation with the sealant supplier.
The calculation and dimensioning of the sealant joint is under responsibility of the manufacturer of the
insulating glazing units.
AGC recommends to assess the aesthetics by means of a mock-up sample.
Additional recommendations:
 Any impurities on the coated surface can be removed using a compressed dry-air jet.
 AGC recommends using clear-coloured enamels that have a sufficiently high energy reflection
level. A dark-coloured enamel will have a relatively high energy absorption level and the coating
may be damaged under the enamel during the heating process.
 Similarly, when the coverage percentage is very high and confined to a very small area, the
printed section of the glass may behave differently to the uncovered section in the quench.
 In any case, the final result will depend on the type of furnace used, its parameters, the colour
and type of enamel used and the desired pattern. The processor will have to carry out preliminary
tests, and manufacture some mock-up samples on a case by case basis, to avoid these
problems. AGC is not liable under any circumstances for the outcome of the operation.
 The presence of enamel on the coating changes the optical properties of the final glass product.
