Do not exceed 160ºF (71ºC) at blade
surface. Damage to fiberglass can
occur.
p.
Cure adhesive at 150º - 160ºF (66º - 71ºC)
for 2 hours. Use heat lamp. Monitor
temperature. Use temperature indicating
strips (E413).
Curing time increases rapidly as
temperature decreases. Adhesive
(E43 or E47.1) will not cure below
60ºF (15ºC). Do not count as cure
time any period when temperature is
below 70ºF (21ºC).
NOTE
If heat lamp is not available, a
serviceable cure can be achieved at
70º - 80ºF (21º - 27ºC) in 24 hour.
q.
When cure is complete remove clamps (11),
aluminum sheet (10), Teflon-impregnated
fabric (9), and peel ply (8). Fair the repair as
required. Use abrasive paper (E9).
