This specification coverspolythioether rubber sealing compound that is fuel resistant, supplied as a two component system which cures at room temperature.

This product has been used typically for contact with fuel, but usage is not limited to such applications. Each application should be considered separately. Polythioether rubber has a service temperature range of -65 to +320 degrees F (-54 to +160 degrees C), with short-term recurring exposures (approximately 6 hours) to 360 degrees F (182 degrees C). It can be used for faying surface and fillet sealing and fastener overcoating. This product is not recommended for use in aerofairing, on aircraft windshields, on canopies or other applications directly exposed to weather. Sealing compound must be applied at temperatures above 50 degrees F (10 degress C), but will cure at lower temperatures.
