Windows and Glass: Service and Repair
Glazing
In order that the design condition of the vehicle is preserved when direct glazing repairs are carried out, it is essential that only approved materials and processes are employed.
Glass and Body Preparation
Betaseal HV3 System methods and materials, are used on all Jaguar vehicles. Ease of working and extended process time can however be gained by ensuring that the vehicle body and replacement glass are at a minimum room temperature of 20 degrees C prior to adhesive application and fitting.
In the event of damage to the body flange finish, rectify as appropriate with the full paint refinishing process as described in the Paint Refinishing Manual.
Adhesive Application Temperature
The specified adhesive has a high viscosity and is not easily applied at 'room temperature' using conventional methods. When the adhesive is applied it chills rapidly on contact with the body and reverts to the hard condition, providing retention strength within minutes.
Raising the temperature of the adhesive will reduce viscosity and speed up the flow. It is recommended that the adhesive is pre-warmed in a heated cabinet for a minimum of twenty minutes and applied with an extrusion gun incorporating integral heating elements.
Adhesive Application
CAUTION: The glass will not bond to the body if the time taken to apply the adhesive and position the glass, exceeds the stated limit.
NOTE: The depth of the glass and thus the thickness of the adhesive, is controlled by the screen rubber contacting the body flange.
It is recommended that the bead of adhesive conforms to the shape and dimensions shown in the Adhesive Application illustration and is positioned along the edge of the rubber.

Adhesive Curing
The specified adhesive cures by exposure to moisture (not by heat). Cure times may vary considerably dependent upon ambient humidity levels. Initial 'chill off' will occur within 1 to 4 minutes (dependent upon the application temperature and rate of cooling), after which the screen must not be moved.
