51 31 ... Notes On Window Bonding Repair Kit
Small repair kit 83 19 0 444 141 contains the following separate component:
Large repair kit 83 19 0 444 145 contains an additional window glass adhesive 300 ml.
IMPORTANT:
Before working with the consumables, note the following information.
- Country-specific safety and industrial safety regulations
- Material safety data sheet of manufacturer
- Processing instructions on the packaging
1 Storage and processing of all consumables
Dry at 15° - 25 °C.
2 Expiry date of adhesive:
Repair kit and glue cartridges are marked with a date (expiry).
Date (1) refers to the calendar week and year (KW/JJJJ).
The adhesive cannot be used after this date (1).
3 Hardening of adhesive:
The adhesive hardens by reacting with air humidity at room temperature.
IMPORTANT:
- Once the adhesive bead has been applied, the window glass must be installed within 7 minutes (depending on air humidity, temperature).
- After 7 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
At ambient temperatures above 23 °C and 50 % relative air humidity (hot countries), the adhesive open time is shortened to approx. 5 minutes (skin formation time).
A relative humidity of < 30% significantly slows hardening.
The adhesive hardening process is interrupted completely at ambient temperatures below 5 °C. In this event, there will be no increase in t he strength of the bonded connection.
3.1 Minimum hardening time:
Minimum hardening time is reached beginning at 22 °C and 38 % relative air humidity.
- 1 hour, vehicles without front passenger airbag (after which vehicle can be moved)
- 2 hours, vehicles with front passenger airbag in countries without mandatory seat belt usage
NOTE:
- In vehicles with front passenger airbag in countries without mandatory seat belt usage:
- The vehicle can be transferred to the customer after a 1-hour hardening time with the following warning:
- Once the windscreen glass has been bonded, all occupants must travel with their seat belts attached for 1 hour.
IMPORTANT: If the minimum hardening time is not adhered to, an accident can cause the passenger together with the windscreen to fall out of the vehicle after the front passenger airbag deploys.
During the minimum hardening time of 1 hour, the vehicle must not be subjected to load on one side such as e.g.:
- one wheel on kerb
- vehicle hoist
- etc.
Manoeuvring inside garage/workshop:
- only permitted on level ground
- do not under any circumstances drive over approach ramps, e.g. into multistorey car parks
Do not remove adhesive tapes until after hardening time.
If the minimum hardening time of 1 hour is undercut, leaks and wind noises may occur at the window glass.
4 Disposal of adhesive:
Hardened adhesive is disposed of as normal waste.
Non-hardened adhesive, glue cartridge and mixtures of adhesive and solvents and the like must be disposed of as hazardous waste.
The adhesive is disposed of in paper sacks so that it can react with moisture.
5 Glass/paint activator (bonding agent):
WARNING: Wear cut resistant gloves when breaking the glass ampule.
Prepare glass activator and paint activator for application by shaking and snapping (breaking glass ampule).
Apply glass activator by pressing gently. There is no need for final wiping. Air drying time approx. 2 minutes.
Apply paint activator by pressingly gently. Then wipe dry with a paper towel (included in the set).
6 Expiry date of bonding agent:
Repair kit and bonding agent are marked with a date (Best Before).
- The bonding agent may only be used up to this date (if not already opened previously).
- After opening, keep only for one week even if the expiry date has not yet been reached.
7 Disposal of bonding agent:
Bonding agent must not be disposed of in household trash.
Bonding agent must be disposed of as hazardous waste.
