Reduced strength will result if the incorrect
mix ratio is used, if an excessive amount
of air is introduced into the adhesive during
mixing, or if mixing is inadequate and may
result in loss of structural integrity.
Pressure must be applied to adhesive within
the pot life of the resin. For ambient temper-
atures in excess of 90 F, decrease this time
by 50%. An unsatisfactory repair will result
if the resin gels before adequate pressure is
applied and may result in loss of structural
integrity. Select and prepare a heat blanket
(if required) and all necessary vacuum bag
materials prior to mixing resin.
(h) Prepare a small amount of adhesive (25
grams) as described in paragraph 6-17
and apply adhesive to the grommet and
fastener hole mating surfaces.
(i)
Install and lare grommet into coun-
tersink (see igure 7-62) with grommet
installation tool. See system speciic
technical manual for any torque require-
ments.
