 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.
