NOTE: The recommended temperature range for both the vehicle surface and the part during application is 18 - 40 °C (64.4 - 104°F). Additional heat is not required for 3M pressure sensitive adhesives.

The 3M Way

Local manufacturing experts in Des Moines, IA were able to use their extensive knowledge of automotive design and production to come up with a solid mounting solution.

PT1100 is a 3M Acrylic Plus Tape black foamed acrylic adhesive with additional acrylic adhesive on both sides. Typical applications are attachments of rigid add-on-parts such as spoiler, rocker panel, antenna housings, roof ditch moldings and wheel arch extensions, etc., where an aesthetic bond line is required.

It is cold temperature impact resistant and does not allow the gurney flap to have play after installed unlike many adhesives would.

A pull test with a Wagner force gauge was performed on the gurney flap. It resulted in 21-22 lbs of force before peel in zones 1 / 3 and over 50 lbs in zone 2 before the gauge moved along the axis of the gurney flap. These single point tests suggest much higher adhesion strength along the entire surface of the flap.

3M rates their tape at a 90 degree peel adhesion for 44 newtons per centimeter. This converts to about 25 lbs per inch of tape. The gurney has the force applied to the tape at approximately a 75 degree angle from horizontal. This gives an even larger factor of safety.

Pre Bent

In order to relieve the tension found in a flat piece of metal, the gurney flap takes a journey through a roll bender. This machine has been programmed to match the curve of the OEM spoiler. This was a key element that allowed proper installation without mechanical fasteners.
