Urethane Adhesive Installation of Encapsulated Stationary Windows
IMPORTANT: Remove all but 1 mm (.040 in) of the existing urethane adhesive from the pinch weld flange. This will ensure proper depth of window
in relations exterior trim.
1. Remove all mounds or loose pieces of urethane adhesive from pinch weld areas.
2. If the original window assembly is being reused, remove all but a thin film of existing urethane from the window frame surface by using a clean
utility knife or razor blade scraper.
IMPORTANT: If corrosion of the pinch weld flange is present or if sheet metal repairs or replacement 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,
Martin-Semour5120. PPG DP90LF, Spies/Hecker 3688/8590 3688/5150 4070/5090. and Standox 11158/13320 14653/14980 are approved for
this application.
3. Clean around the inside edge of the window assembly with a 50/50 mixture of isopropyl alcohol and water on a dampened lint free cloth.
4. Verify all primers an urethane adhesives are within expiration dates.
CAUTION: Refer to Window Retention Caution in Cautions and Notices.
5. Failure to prepare the area prior to 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 of urethane adhesive on the pinch weld flange. Apply the primer only to
nicks, scratches or the primed surfaces.
6. Shake the black #3 primer for at least 1 minute.
7. Use a dauber in order to apply the primer to the surface of the pinch weld flange.
8. Allow the pinch weld primer to dry for approximately 10 minutes.
9. With an assistant, dry fit the window assembly into the opening to determine correct position.
10. Using masking tape, mark the location of the window assembly to the opening.
11. Apply Glass Prep #1 followed by Glass Primer #2 on the encapsulation material. Allow to dry for 6 to 10 minutes.
12. Cut the applicator nozzle in order to provide a bead of 10 mm high (1) and 6 mm wide (2).
