- primer layer is meant a layer of an organic product which adheres well to the peripheral seal and which has selective adhesive properties vis-à-vis the glass or the transparent resin which is made the spacer .
- examples of such primers are based on compounds of the family of silanes and compounds of the family of acrylic resins.
- Good adhesion is understood to mean an adhesion which requires a positive tearing force to separate the two assembled parts and whose rupture of the two parts between them is cohesive, as described in the EN 1279 part 4 standard.

- the insulating glazing unit comprises at least a first and a second glass sheet associated via the intermediate frame, said sheets being of different sizes and therefore able to be offset on part or all of the periphery of the glazing.
- This is called asymmetric or remote glazing.
- This difference in size between the first and second glass sheets has the advantage of facilitating the insertion of a reinforcement and a fastening system.
- the interest here is also to allow translational opening / closing systems (sliding doors).
- Another advantage of this particular embodiment of the invention is to allow the placement of a heating network that could be deposited on the part of the offset glass to prevent the appearance of condensation at the edge of glazing.

- the enamel layer is applied to the glass sheet which is directed towards the outside of the refrigerating cabinet.
- the fastening system is masked by the decorative layer deposited on the glass sheet.
- an enamel layer is deposited on the offset surface of the glazing unit and makes it possible to hide the system for fixing the view of an outside observer.
- the glass sheets are sheets of toughened glass or sheets of laminated glasses.
- the latter comprise a stack of at least one sheet of polyvinyl butyral plastic (PVB) disposed in sandwich between two sheets of glass.
- PVB polyvinyl butyral plastic

- the desiccant is integrated into the matrix of the Super Spacer ® spacer.
- a 1 mm thick polyisobutylene bead was placed over the entire length of the horizontal spacers (12) as shown in FIG. 4. This polyisobutylene cord acts as the first double horizontal peripheral seal (8).
- a 3M VHB ® double-sided acrylic adhesive tape seal 4918 of 2 mm thickness and 10 mm height was deposited along the entire length of the vertical spacers (11) as shown in FIG. to increase the adhesion between the acrylic adhesive and the glass sheet, a 3M ® AP 115 silane primer was deposited at each interface.
- an internal space (7) comprising a plate of an insulating gas of argon type is closed by the spacer frame (6).
- the concentration of Argon is 85%.
- a second horizontal Dow Corning ® 3362 silicone peripheral seal (9) (hereinafter referred to as a "silicone seal") was placed along the horizontal edges and is contiguous to the horizontal spacers. (12), the first horizontal peripheral seal (8) and the two glass sheets (4, 5).
- the stiffening element (15) has also been immersed in the silicone seal (9).
- a U-shaped section, having the role of reinforcement (14), is inserted into the silicone seal (9).
- the reinforcement (14) is made of stainless steel and extends along the horizontal spacer (12).
- a fastening system (13) has been partially inserted in the second horizontal peripheral seal (9) and in the reinforcement (14).
- the fastening system (13) was composed of the following elements: two screws 5 mm in diameter, and a pivot piece contiguous to the silicone seal (9) and equipped with two holes where the two screws were inserted . The screws also came insert into the silicone seal (9) and the U-profile (14). This fastening system (13) has secured the door (1) to the refrigerating cabinet (2).
- EXAMPLE 2 Effect of a Primer Materials: - Rectangular plates made of soda-silico-calcic float glass, 4 mm thick and 65 mm x 25 mm in size.
- Test tubes with primer Two test pieces are made, each from two rectangular plates of silico-soda-lime float glass, one of which has been previously coated (on one side) with a TopN + T low-emissive layer.
- One of the two faces of the non-pre-coated wafer and the pre-coated face of the second wafer are cleaned with isopropanol.
- the primer is then applied to the cleaned surfaces under a controlled atmosphere at a temperature of 25 ° C and 50% relative humidity (RH).
- the primer dries for 2 to 3 minutes before applying a 25 x 10 mm tape strip transversely to one of the glass plates so as to cover its entire width in the center position of the wafer, avoiding the formation and trapping of any air bubble between the tape and the glass plate.
- the second glass plate is then glued in its central position on the other side of the tape already adhered to the first glass plate so that the glass plates form an angle of 90 ° between them.
- a glass / layer stack low-e / primer / double-sided tape / primer / glass has been produced.
- a reference test tube and a test tube with primer were placed for 336 hours in a chamber under a controlled atmosphere at a temperature of 70 ° C. and 100% RH.
- a reference test tube and a test tube with primer were not subjected to this conditioning.
- test pieces were then subjected to a mechanical test consisting in pulling the two glass plates of each test piece.
- the test was carried out under a controlled atmosphere at a temperature of 25 ° C. and 50% RH.
- the traction was exerted in a direction perpendicular to the surface of each of the two glass sheets and the pulling force necessary to cause tearing and complete separation of the two wafers was measured.
- the rupture is of cohesive type inside the material of the tape, except in the case of the sample without primer having undergone a conditioning.
- the latter exhibits a phenomenon of delamination of the adhesive from the conditioning phase and gives rise to an adhesive rupture at the coated glass interface of the low-e / tape layer.
- test piece made according to the particular variant of the invention has an increased resistance to aging performance compared to a reference test piece.
