General notes on the use of adhesives

Safety data sheets

♦ Observe → safety data sheets.

Storage limitations

♦ It is not permissible to process adhesives, activators or primers if the specified shelf life has elapsed.

Important

● Opened primer or activator bottles must not be used any further.

● Only use materials whose packaging does not show any signs of damage.

● Do not use adhesives, primers and activators if the colour and consistency are not stable.

♦ Storage temperature between 10°C and 25°C

Specifications for use of paste-like adhesives

♦ Observe the specifications for handling Volkswagen special tools and cartridge openers in the → operating instructions of the tool.

♦ Vehicle, components, adhesive, primer and activator must have acclimatised before processing.

♦ Before starting any work on the bonding surfaces, make sure that the processing temperature has been reached.

♦ Do not carry out welding, grinding and polishing work in the immediate vicinity.

♦ Do not use Teflon or silicone sprays in workshop area.

♦ Cleaned surfaces should only be touched with clean gloves to avoid the transfer of hand sweat and dirt to the bonding surfaces.

♦ Adhesives must be used within the processing time.

♦ The adhesive must be applied and the window or body component joined within the processing time.

♦ Any joining work (e.g. riveting, bolting) in the area of the adhesive bond must be carried out within the processing time.

♦ Make sure that the vehicle is not exposed to any load before the minimum curing period has elapsed.

♦ Do not start any further work on the vehicle until the minimum drying time has elapsed.

Applies for 2-component adhesive

Important

● Press the cartridge and check that both components escape evenly. Then fit the mixing tube.

● To ensure thorough mixing, squeeze out a mixing tube length of fresh adhesive onto a piece of cardboard, and discard before application.

● Due to the risk of the curing process starting, opened 2-component window adhesive cartridges with part number “D 004 660 M4” must not be stored for later use, but must be disposed of together with the mixer after the processing time has expired.

● Opened plastic adhesive cartridges with part number “D 180 KU2 A1” must not be stored for later use for longer than 14 days due to the risk of the curing process starting. They must be disposed of together with the mixer once the processing time has expired.

Bonding log, inc. working sample for bonding operations that require documentation – introduction and overview

Introduction

For certain bonding processes, new design requirements are placed on the processes of joining or bonding. The internal and external modifications implemented by the manufacturer are based on the updated state of the art in accordance with ISO 21368, in view of:

♦ the increasing importance of bonding in the automotive industry, and of the fact that

♦ bonding is a "special process" that does not allow for the quality of the bond to be tested non-destructively.

Modifications of Workshop Manual

If relevant in terms of design, the vehicle-specific workshop manuals of the upcoming vehicle models will include additional information on:

♦ creating and carrying out working samples;

♦ qualification of personnel; and

♦ filling out the bonding log.

In the bonding log, the bonding process as well as the materials used and the corresponding working sample must be fully documented in accordance with the respective repair description. This is necessary as a proof of the reliability of the bonding process.

The bonding log has been agreed with the brands VW Passenger Cars (VWPKW), Volkswagen Commercial Vehicles, Audi, Škoda and Seat, and will also be introduced by these brands with the upcoming vehicle models.

Qualification

A training module for qualification as a "Volkswagen Group bonding expert", coordinated within the Volkswagen Group, will be made available via the brand-specific “Knowledge Tank”. This training module includes a theoretical and practical final examination for the certificate. Successful participation in this training is recommended to make sure bonding work is carried out in accordance with the relevant safety requirements.

Minimum drying times for bonded windows

Minimum drying times for bonded windows

Special requirements must be considered when replacing bonded windows.

The minimum drying time is the time from bonding in until the vehicle is ready to be used.

The vehicle is safe to use only after the minimum drying time has elapsed.

For the minimum drying time, refer to the processing instructions on the manufacturer’s label.

During the minimum drying time, the vehicle must be standing on a level surface.

The minimum drying time for 2-component window adhesive is 2 hours at a room temperature of between 18 °C and 35 °C (64.4 °F and 95 °F).

The minimum drying time for 1-component window adhesive is 6 hours at a room temperature of between 20 °C and 30 °C (68 °F and 86 °F) with a relative humidity of between 30 % and 80 %.

Note

The figure shows 2-component window adhesive. For 1-component window adhesive, proceed analogously.

– Apply window adhesive -1- in continuous bead, holding applicator at right angle to window glass -2-.

Note

Don not apply adhesive bead too thick or press glazing too firmly onto the body flange. Since the glazing no longer has sealing lips, excessive window adhesive may be visible in the joint area.

– Using 2 suction lifters -V.A.G 1344-, insert glazing into window aperture, align it to centre and press it in up to spacing lip.

– During the minimum drying time, fix windows in position using commercially available adhesive tape → General information – body; Rep. gr.52; Use of adhesives; General notes on the use of adhesives.

– When renewing components, identification labels from old parts indicating the corresponding spare part numbers in the → Electronic parts catalogue (ETKA) must be attached to the respective new parts as required by registration regulations.

– Renew any illegible or damaged identification labels and information or warning signs found on components of this vehicle, and affix the new ones in the same location. For allocation, see → Electronic parts catalogue (ETKA).

Bonding log

Bonding log

Introduction

The requirements for the processes of joining or bonding vary depending on the component. These include, for example, the preparation of a bonding log.

This is necessary as a proof of the reliability of the bonding process.

Important

● A bonding log must be prepared if specified accordingly in the respective repair description.

● In the bonding log, the bonding process as well as the materials used and the corresponding working sample must be fully documented in accordance with the respective repair description.

Working sample

Important

● Ensures and proves that bonding has been carried out correctly.

● The result of the working sample must be documented in the bonding log.

● To create a working sample, apply a bead of adhesive of approx. 10 cm in length to a solid substrate, and evaluate it once the specified minimum drying time has elapsed.

● For evaluation, cut the working sample with a commercially available cutter in several locations, and assess the hardening effect by examining the cut surface.

Exams on working sample with 1-component adhesive bead:

♦ The adhesive must have a firm skin and may not pull threads when touched.

♦ No liquidity must be evident inside the adhesive bead after the minimum drying time.

Exams on working sample with 2-component adhesive bead:

♦ The adhesive must be fully hardened.

♦ No liquidity must be evident inside the adhesive bead.

If the result of the working sample is negative (hardening not complete), process-safe bonding is not ensured. If this is the case, measures need to be taken to ensure proper hardening, which involves consulting the bonding supervisor (four-eyes principle) and, if necessary, repeating the bonding process.
