• Trowelable for edge filling and repair of cracks, scratches, and defects. Also useful for the densification of honeycomb cores.
• Capable of complete cure at room-temperature to eliminate the need for ovens
• Excellent adhesion to syntactic and various metal surfaces
• Qualified to Boeing Spec SCGMS 58001& Lockheed Spec STM M1130
• Exceeds NASA outgassing requirements for high vacuum environments
