OOA Epoxy Film Adhesive
Henkel Corporation Aerospace (Bay Point, Calif.) reports that its Hysol PL 7000
epoxy film adhesive for aerospace applications is now out-of-autoclave (OOA) curable.
In addition, the mechanical performance of the adhesive is said to be equivalent
to the standard cure performance of a film that has been cured in an autoclave.
Also new is Hysol PL696, an epoxy-based structural film adhesive, designed primarily
for OOA curing process applications. Also available in lightning-strike configuration,
the adhesive can be cured conventionally via vacuum bagging at 140°F/60°C and can
bond a variety of similar and dissimilar materials. The adhesive also meets the
requirements of military specification MMM-A-132. A third new product is Hysol EA
9896 WPP (wet peel ply) composite bonding film, a resin-impregnated nylon peel ply
used for the surface preparation of composite substrates. It reportedly eliminates
the need for sanding or grit blasting in the surface preparation process. It also
eliminates residual peel ply fibers at the bond surface after curing and removal.
The product , according to the company, is currently under evaluation by aerospace
customers.
