PR–1005-L
Especificación militar MIL-S-4383
|
|
|
|
|
|
PR-1005-L is an aircraft integral fuel tank slosh coating.
It has a service temperature range from
(-73°C) to (121°C), with intermittent excursions
up to (135°C). This material is designed
as topcoat or barrier coating. The cured coating is
resistant to prolonged exposure to both jet fuel and
aviation gas.
PR-1005-L is a one part, synthetic rubber solution.
The uncured material is a thin syrup suitable for
application by brush, fill-and-drain, dip or spray.
It cures at room temperature by the evaporation of
solvent to form a smooth, tough, flexible transparent
film having excellent adhesion to common aircraft
substrates and polysulfide sealants. |

exposure to both jet fuel and aviation gas.
PR-1422 Class B is a two part, dichromate cured polysulfide
compound. The uncured material is a low sag,
thixotropic paste suitable for application by extrusion
gun or spatula. It cures at room temperature to form a
resilient sealant having excellent adhesion to common
aircraft substrates. |
