Permabond Adhesives for Fire Protection
Leaking sprinkler systems can cause costly damage to ceilings, floors, furnishing and other valuables. Permabond metal pipe sealants and weld sealants are relied upon to prevent leaks.
Typical Applications:
- Sealing metal pipe connections
- Weld sealing
- Sealing sprinkler heads into pipework
Adhesive Key Features
Permabond Metal-Pipe Sealant with PTFE
Permabond Metal-Pipe sealants use anaerobic technology to prevent leaks in sprinkler systems. Used in fabrication and installation, Permabond sealants replace pipe dope and sealing tapes with a complete and reliable seal.
- UL listed for sprinkler systems (Permabond LH050)
- 100% Leak free seal even when pipe is not completely seated
- Eliminates "call back" repair costs
- Seals cut and miss-threaded fittings
- Open container will not dry out
- Won't "thin" in summer
- Won't "thicken" in winter
- Replaces pipe dope and tapes
- Prevents corrosion
- Easy disassembly with hand tools
- Lubricates to ease assembly
Permabond sealants for metal pipes do not remain a paste (like pipe dope), but cure to a solid plastic seal. Cure is initiated by the presence of metal and the absence of air.
Permabond Weld Sealants
Permabond anaerobic sealants prevent porosity leaks in the welds of sprinkler system fabrication and repairs porosity leaks in the field.
- Use in fabrication to prevent leaks in the field
- Eliminates "call back" repair costs
- Easy to use
- Seals leaks in the field
Permabond weld sealants fill all voids or imperfections and cure to form a permanent plastic seal that prevents potential leaks. Cure is initiated by the absence of air and the presence of metal, and begins to occur when the sealant wicks into the imperfections.
