Prepare the Motorcraft TA-1 or TA-1-B adhesive by placing the cartridge into an applicator gun and dispensing a small amount of adhesive to
level the plungers. Install a mixing tip onto the cartridge then dispense a 75 mm (3 inch) bead of adhesive onto a piece of scrap cardboard to make
sure the components are properly mixed and ready for application.
NOTE:
TA-1 adhesive has a working time of about 40-50 minutes at 21 °C (70°F).
^
For about every 10°C (20°F) ABOVE 21 °C (70°F), the working and cure time is cut in half.
^
For about every 10°C (20°F) BELOW 21 °C (70°F), the working and cure time are doubled.
