sealing<br />

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 />
