Two-component;<br />
Low (down to +20 ºF / -7 ºC) and<br />
ambient temp. curing; Type I,<br />
Grade A1 only - can be heat cured<br />
at temps. up to +350 ºF (+175 ºC)<br />
Service temp: -80 ºF to +300 º F<br />
(-68 °C to +150 °C) with intermittent<br />
use to +400 °F (+204°C) for<br />
Type I & +360 ºF (+182 ºC) for<br />
Type II;<br />
Peel strength: 20 lb/in width<br />
(min);<br />
Corrosion inhibiting - Type II<br />
only; Type I has no corrosion<br />
inhibitors;<br />
Resists fuel, oil, and hydraulic<br />
fluid.<br />
Multi-purpose structure and<br />
integral fuel tank sealants<br />
with rapid ambient and low<br />
temperature curing capabilities.<br />
Use of manufacturer's<br />
recommended primer is<br />
required prior to applying<br />
this sealant for proper adhesion.<br />
Type I can be used as<br />
an alternate for SAE AMS-S-<br />
8802 (MIL-S-8802) in fuel<br />
tank applications and Type II<br />
can be used as an alternate<br />
for MIL-PRF-81733.<br />
NOTE: Although this sealant<br />
was originally intended for<br />
sealing aircraft structures, it<br />
is included here because it is<br />
used for other applications.<br />
