Cleanup

Excess adhesive can be cleaned up, prior to curing, with Toluol* or Ketone* type

solvents.

*Note: When using solvents, extinguish all ignition sources and follow the

manufacturer’s precautions and directions for use.

Product Performance

Note: The following technical information and data should be considered representative

or typical only and should not be used for specification purposes.

1. Prepare overlap sheer bonds in the manner described above and allow to cure as

follows:

a. Apply 2 psi bonding pressure uniformly to the bond line using dead weights.

b. Allow panels to cure undisturbed at a temperature of 75°F (24°C) for 24-48

hours.

In addition to the standard room temperature cure, the following times, and

temperature will give a minimum of 2000 psi tensile shear strength.
