Description / Abstract:

Form

This specification covers two types of electrically conductive, elastomeric polythioether sealing compounds that cure at room temperature. The sealing compound is supplied as either a two-component system or as premixed and frozen.

Application

These materials primarily provide an electrically conductive sealant or metal joint interface for shielding purposes. They have been used in aircraft to provide an electrically conductive path in faying surface seals as well as overcoating of fasteners and sealing of seams and joints along with providing an effective corrosion barrier. They have a continuous service use from -65 to +250°F (-54 to +121°C). The cured sealant materials are resistant to exposure to both jet fuel and aviation gas.

Classification

Types

Type 1 - Contains chromate type corrosion inhibitors.

Type 2 - Contains non-chromate type corrosion inhibitors.

Classes

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

B-1

B-2

Safety - Hazardous Materials

Shall be in accordance with AS5502 (1.1).
