Adhesive Application
Key to Adhesive Application Drawing
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.
BUMPER REPAIR\RENEWAL
Bumper Description
Each bumper comprises a beam mounte d to the body via two strut assemblies and a moulded polypropylene cover
incorporating side armatures and chrome plated plastic upper trims. The front bumper cover which is moulded to form a
lower air intake for the cooling pack, also incorporates twin fog lamps, brake cooling ducts and side marker lamps or
reflectors (dependent upon market). A plastic undertray secured to the lower edge of the front bumper and the BIW
improves airflow and minimises the ingres s of road grime in that area. Standard bumpers have glass mat thermoplastic
(GMT) beams mounted on GMT struts. For certain markets, aluminium bumper beams are installed on menasco energy
absorbing struts.
Bumper Cover Repair
1Fitted condition
2Bead application
Prior to commencing any work, bumper damage should be assessed for repairability and categorized in accordance with the
following guidelines. Bumper covers that are torn or holed are not repairable and must be discarded.
CAUTION: Cosmetic appearance must no t jeopardise safety. No attempt must be made to repair bumper covers
damaged beyond category three. Damage of this extent will compromise the protective performance of the cover and it
must be renewed. The thermo-s etting nature of the cover material, preclude s the repair of splits by heat or welding
techniques.
Repair Materials
Repair of accepted damage for categories 2 and 3 may be carried out using 3M '5900 FPRM' (Flexible part repair material)
or Kent Industries 'Urepatch'. Repair product manufacturers' recommendations an d procedures must always be strictly
followed.
Bumper Cover Refinishing
The paint refinishing system must be approved by Jaguar Cars Ltd., and be appropriate for polyurethane substrate
application. It is essential that the fini shing clear lacquer includes a plasticising ingredient (mixed to the manufacturer's
recommendation) that will achieve the 'semi-fl ex' condition of the factory finished item.
Bumper Cover Support
Exposure to heat decreases bumper cover rigidity. Covers removed for repair mu st therefore be supported to prevent
distortion and sagging during the paint curing process. Where the original bumper cover has been repaired, the beam will
provide sufficient support for the centre section. It is recommended that the side armatu res are supported as they would be
on the vehicle. If a new cover is required, the beam may be temporarily fitted to provide the necessary support during
refinishing.
CAUTION: During heat cure, the effective panel temperature must not exceed 95°C.
