Adhesive Installation of Stationary Windows Windshield
Caution: When working with any type of glass or sheet metal with exposed or rough
edges, wear approved safety glasses and gloves in order to reduce
the chance of personal injury.
Important: Remove all but approximately 2 mm (3/64 in)
of the existing bead of urethane adhesive from the pinch-weld flange.
- Remove all mounds or loose pieces of urethane adhesive from the pinch-weld area.
- If the original window is being reused, remove all but a thin film of
the existing urethane adhesive from the window surface by using a clean utility knife
or razor blade scraper.
- Inspect the following components for the causes of a broken window:
• | The flange of the window opening |
• | The window reveal molding |
- Inspect for any of the following problems in order to help prevent future
breakage of the window:
• | Any other obstruction or irregularity in the pinch-weld flange |
Important: If corrosion of the pinch-weld flange is
present or if sheet metal repairs or replacements are required, the pinch-weld flange
must be refinished in order to restore the bonding area strength. If paint repairs
are required, mask the flange bonding area prior to applying the color coat in order
to provide a clean primer only surface. Materials such as BASF DE15®,
DuPont 2610®, Sherwin-Williams PSE 4600 and NP70® and Martin-Semour
5120 and 5130® PPG DP90LF SPIES/ HECKER 3688/8590 - 3688/5150 -
4070/5090 STANDOX 11158/13320 -- 14653/14980 products are approved for
this application.
- After repairing the opening as indicated, perform the following steps:
5.1. | Remove all traces of broken glass from the outer cowl panel, seats, floor
and defroster ducts. |
5.2. | Clean around the edge of the inside surface of the window with a 50/50
mixture of isopropyl alcohol and water by volume on a dampened lint free cloth. |
Caution: When replacing stationary windows, use Urethane Adhesive Kit GM P/N 12346392
(Canadian P/N 10952983), or a urethane adhesive system meeting GM Specification
GM3651G, to maintain original installation integrity. Failure to use the urethane
adhesive kit will result in poor retention of the window which may allow unrestrained
occupants to be ejected from the vehicle resulting in personal injury.
- Verify all primers and urethane adhesive are within expiration dates.
Caution: Failure to prep the area prior to the application of primer
may cause insufficient bonding of urethane adhesive. Insufficient bonding
of urethane adhesive may allow unrestrained occupants to be ejected from
the vehicle resulting in personal injury.
Important: Do not apply the black #3 primer to
the existing bead (1) of the urethane adhesive on the pinch-weld flange. Apply the
primer only to nicks, scratches or the primed surfaces.
- Shake the pinch-weld primer black #3 for at least 1 minute.
- Use a new dauber in order to apply the primer to the surface of the pinch-weld
flange (1).
- Allow the pinch-weld primer to dry for approximately 10 minutes.
- Install the new windshield acoustic strip (1) to the windshield (2),
if equipped or damaged.
The acoustic strip aids in reducing noise.
- Install the windshield locating cams.
- With an assistant dry fit the window (1)
to the opening in order to determine the correct position.
- Using masking tape in order to mark the
locations (1) of the window (2) in the opening.
- Cut the masking in the center and remove the window from the opening.
Important: Use care when applying glass prep clear #1
on the window. This primer dries almost instantly, and may stain the viewing area
of the window if not applied evenly.
- Use a new dauber in order to apply glass prep clear #1 to the area approximately
18 mm (0.71 in) around the entire perimeter of the window inner surface.
Immediately wipe the glass primed area using a clean, lint-free cloth.
- Apply a second coat of the glass prep clear #1 to the same area of the
glass.
Important: The glass primer black #2 is effective
up to 8 hours after applying it to the glass. The primed surface of the glass must
be kept clean.
- Shake the glass primer black #2 for at least 1 minute.
- Use a new dauber in order to apply the glass primer black #2 to
the same areas (2) that glass prep clear #1 was applied.
- Allow the glass primer to dry for approximately 10 minutes.
- Cut the applicator nozzle in order to provide a bead of (b) 8 mm (0.31 in)
wide and (c) 14 mm (0.55 in) high.
- Use
a cartridge-type caulking gun in order to apply a smooth, continuous bead of urethane
adhesive.
- Use the edge of the window or the inside
edge of the reveal molding as a guide for the nozzle in order to apply the urethane
adhesive (1) to the inner surface of the window (3).
- With the aid of an assistant, place the window in the opening.
If installing a windshield place the windshield on the locating cams.
- Align the masking tape (1) lines on the
window (2) and the body.
- Press the window firmly into place.
- Tape the window to the body in order to minimize movement until the urethane
adhesive cures.
- Clean any excess urethane adhesive from the body.
Important: Do not direct a hard stream of high pressure
water to the freshly applied urethane adhesive.
- Use a soft spray of warm water in order to immediately water test the window.
- Inspect the window for leaks.
- If any leaks are found, use a plastic paddle in order to apply extra urethane
adhesive at the leak point.
- Retest the window for leaks.
Caution: Insufficient curing of urethane adhesive may allow unrestrained occupants
to be ejected from the vehicle resulting in personal injury.
• | For the moisture-curing type of urethane adhesive, allow a minimum
of 6 hours at 21°C (70°F) or greater and with at least 30 percent
relative humidity. Allow at least 24 hours for the complete curing
of the urethane adhesive. |
• | For the chemical-curing type of urethane adhesive, allow a minimum
of 1 hour . |
Do NOT physically disturb the repair area until after these minimum
times have elapsed.
- Maintain the following conditions in order to properly cure the urethane adhesive:
• | Partially lower a door window in order to prevent pressure buildups when
closing doors before the urethane adhesive cures. |
• | Do not drive the vehicle until the urethane adhesive is cured. Refer to
the above curing times. |
• | Do not use compressed air in order to dry the urethane adhesive. |
- Complete the window installation.
