This specification covers six (6) types of sealing compounds curing to elastomeric materials.

These products are used primarily for sealing aircraft firewall structures against passage of air and vapors but usage is not limited to such applications. The sealing compounds are effective at all temperatures from -65 to +400 degrees F (-54 to +204 degrees C) and are able to withstand flash temperatures of up to 2000 degrees F (1093 degrees C).
