    Overview

    PPG PS700 is a high-temperature, primerless firewall sealant designed for sealing aircraft firewall structures against air and vapor passage. This two-part synthetic rubber compound cures at room temperature to form a resilient, flame-resistant barrier used across aviation maintenance, repair, and overhaul (MRO) operations. Maintenance teams rely on P/S 700 for its ability to withstand extreme temperatures, harsh fluids, and demanding aircraft environments while remaining easy to apply in both production and field repairs.
