CURED SPEED VS. GAP
The rate of cure will depend on the bondline gap. Thin bondlines result in high cure speeds, increasing the bond gap
will decrease the rate of cure.
CURED SPEED VS. ACTIVATOR
Where cure speed is unacceptably long due to large gaps, applying activator to the surface will improve cure speed,
However, this can reduce ultimate strength of the bond and therefore testing is recommended to confirm effect.

DIRECTIONS FOR USE
For best results the surface must be clean and free from oil ,grease, rust and other contamination. Best results with
DEDT adhesive are obtained by using the minimum amount of adhesive needed to fill the gap between the two
mating surfaces. Apply firm pressure to mated surfaces until adhesive sets.
