FM 300-2 film adhesive,
a 250°F/120°C cure version of Cytec Engineered Materials’
widely used FM 300
film adhesive, delivers the same superior high temperature
performance, toughness and stress strain properties
of FM 300 film adhesive without
requiring a 350°F/175°C cure cycle. In addition, FM
300-2 film adhesive's processing window includes temperatures
up to 300°F/150°C providing a unique level of flexibility
from one adhesive product.
FM 300-2
adhesive was developed specifically for co-cure and
secondary composite bonding applications. Through innovative
curative technology, the required cure temperature is
reduced allowing for secondary bonding of structure
far below the composite's glass transition point. FM
300-2 film adhesive also offers optimum flow control
desirable for co-cure composite bonding. FM
300-2 is also commonly used as a surfacing film.
In metal bond applications, FM 300-2 film
adhesive provides excellent moisture and corrosion resistance
in high humidity environments with a minimal reduction
in mechanical properties. To achieve consistent mechanical
performance as well as maximum environmental resistance
in bonding metallic details, the use of pre-cured BR
127 corrosion inhibiting primer is recommended.
FM 300-2 adhesive is available as an unsupported or
suported film employing both knit and random mat carriers.
A low-flow version of FM 300-2 film adhesive
for composite interleaving, designated FM
300-2 interleaf adhesive, is also available.
