Description / Abstract:

Form

This specification covers temperature resistant, two-component synthetic rubber compounds of the polysulfide type for sealing and repairing integral fuel tanks and fuel cell cavities, for continuous service use from −65 to +250 °F (−54 to 121 °C).

Application

This sealing compound has been used typically for fuel tank sealing, cabin pressure sealing, and aerodynamic smoothing, but usage is not limited to such applications. It can be used for faying surface sealing, for wet-installation of fasteners, for overcoating fasteners, and for sealing joints and seams. The sealing compound can be used in fuel areas as well as in non-fuel areas. It may in some cases be used as a non-structural adhesive. It cures at room temperature and the cure can be accelerated by higher temperatures.

AMS 3100 adhesion promoter can be applied prior to application of the sealant.

Classification

Sealing compounds covered by this specification are classified as follows:

Type 1 - Dichromate Cured Sealant. Material with a dichromate curing agent.

Type 2 - Manganese Dioxide Cured Sealant. Material with a manganese dioxide curing agent.

Both Type 1 and Type 2 sealing compounds shall be supplied in the following classes:

Class A - Suitable for application by brush. Available in the following application times in hours:

A-1/2

A-1

A-2

Class B - Suitable for application by extrusion gun, spatula, brush, or roller. Available in the following application times in hours:

B-1/2
