PPG PR1772B-2 (100-ml-Semkit)

Additional Product Information

Aircraft engineers and MRO teams working on everything from the most advanced military aircraft to passenger airlines carrying millions of people each year rely on PPG PR1772B?2 because it delivers OEM?approved sealing performance with up to 30% weight savings. This Class B?2 polysulfide sealant is trusted across the aviation industry for fuselage structures, joints, and fuel tanks, where corrosion protection and fuel resistance are critical to safety. Ground crew keep it in stock because in AOG situations, having PPG PR1772B?2 ready means aircraft can be sealed, protected, and returned to service without delay. When safety and compliance cannot be compromised, this sealant is the proven choice for MRO operations worldwide.
