P/S 700 - Firewall Sealant
P/S 700 is a high-temperature primerless firewall sealant with a service range from -65°F to 400°F and can withstand flash temperatures up to 2000°F. This two-part synthetic rubber compound is a low-sag paste that can be applied with an extrusion gun or spatula. It cures at room temperature to form a resilient seal against air and vapor passage in aircraft firewall structures.
