CheckSeal™ 9B & 9F
Thermosetting Sealant
Check Seal™ 9B & 9F are sealants with heavy fibers that cure upon the application of heat to form a very hard set solid sealant which blocks leak paths. Check Seal™ 9B is a thermosetting resin reinforced with a fibrous bulk material and works great with boilerfeed water leaks. Check Seal™ 9F is a thermosetting resin more heavily fibered material for improved sealing traits and higher temperature performance up to 1500°F, such as high temperature catalyst flue gas leaks.
Recommended Uses
It is used in a wide variety of industrial applications including sealing wire wraps, clamps and enclosures.
