Anaerobic Threadlocker

Anaerobic Adhesive

The word "anaerobic" means "without air", which means that these adhesives cure on removal of air (oxygen). The other pre-condition for anaerobic adhesives to cure is that they need to be in contact with a metal. Hence, anaerobic adhesives remain in liquid form until they are isolated from oxygen and come in contact with metals like iron, copper, etc. Anaerobic adhesives fill the gaps between metal components in an assembly (for example, a nut and bolt assembly). It is because of this property that they are used to augment the seal or hold components of a mechanical assembly together – all these applications usually require high shear strength.

Parson Adhesive Inc. is one of the leading manufacturers for a wide range of high-quality anaerobic adhesives for industrial engineering applications. Sonlok® range of anaerobic adhesives is used globally by a wide spectrum of industries spanning from electronics to automotive companies. The anaerobic adhesives include thread locking, thread sealant, retaining compound, and gasketing compound. Some grades are certified to NSF, Military, NSF and WRAS specifications.

SONLOK® 3555 PIPE SEALANT FOR FIRE SPRINKLER SYSTEMS

SONLOK® 3555 Pipe Sealant and SONLOK 3290 weld sealant are excellent products of choice of fire protection professionals.

SONLOK 3555 Pipe Sealant uses unique anaerobic technology with Teflon ® to prevent leaks in sprinkler systems. SONLOK 3555 Pipe sealant widely used in fabrication and installation to replace pipe dope and sealing tapes with durable and reliable seal.

SONLOK 3555 sealant provides an instant seal of 1,000 psi and a cured seal that surpasses the burst rating of most of the pipes. Due to its unique Teflon ® filled technology and smooth nature, the assembly will require less effort, and eliminate excess wear and tear on installers and equipment.

  • UL listed for sprinkler system
  • Replaces Pipe Dope and Tapes
  • Lubricates To Ease Assembly
  • Easy disassembly with hand tools
  • Open container will not dry out
  • 100% leak-free seal even when the pipe is not completely seated
  • No solvent, no shrinkage, lower cost, less downtime
  • High temperature resistance, Cures on metals in the absence of air

SONLOK® 3555 Pipe Sealant with PTFE Fabrication and Field Installation Instructions:

  • Apply 3555 onto leading 3-4 threads halfway around the male pipe for sizes up to 1 ½ inch. For larger pipe sizes apply completely around the pipe.
  • Fasten fittings together. 3555 will seal even when the pipe cannot be ‘driven home’.
  • Visually inspect for a white bead of pipe sealant around the entire pipe. Repeat steps 1 and 2 as necessary.

SONLOK® 3565 PIPE SEALANT

SONLOK® 3565 is an anaerobic pipe sealant with paste-like consistency. The anaerobic sealant cures in the absence of air between close-fitting metal surfaces.

SONLOK® 3565 develops controlled strength to facilitate disassembly.

  • Apply 3555 onto leading 3-4 threads halfway around the male pipe for sizes up to 1 ½ inch. For larger pipe sizes apply completely around the pipe.
  • Fasten fittings together. 3555 will seal even when the pipe cannot be ‘driven home’.
  • Visually inspect for a white bead of pipe sealant around the entire pipe. Repeat steps 1 and 2 as necessary.

SONLOK® 3290 WELD SEALANT

SONLOK® 3290 Weld Sealant is an anaerobic sealant that prevents 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
  • Seals leaks in the field
  • Easy to use one component system

SONLOK® 3290 Weld Sealant fills all voids or imperfections and cures to form a permanent plastic seal that prevents potential leaks. A cure is initiated by the absence of air and the presence of metal and begins to occur when the sealant wicks into the imperfections.

 

COPPER SEAL® IDEAL WAY TO BOND COPPER PIPES

Copper Seal® solderless bonding agent for Copper pipes and fittings is the fastest, easiest way to permanently install or repair rigid copper pipe in office buildings, industrial complexes, shopping malls, residential, hotels, manufacturing facilities, apartment buildings, farms, barns, homes. Designed to be used on all rigid copper pipes, fittings, and connectors that carry water including drinking water.Copper Seal® provides a cold weld between rigid copper pipe and copper fittings and connectors. It is very reliable, permanent and durable as a hot solder weld, and is an innovative solution to the time consuming and dangerous hot soldering method of connecting rigid copper pipe to connectors and fittings.

  • Non-toxic and 100% safe to use
  • Save 75% in installation & repair time
  • Excellent weld strength 1,000 psi official rating

Frequently Asked Questions

Anaerobic literally means "without air", in other words, and  removal of air (oxygen) is required for adhesives to cure. For anaerobic adhesive to cure, it must have contact with metal ion or with any metal to have reactivity. Anaerobic adhesives are generally used for metals and not recommended to be used for plastic parts sealing or locking

 

  • 1 component adhesive 
  • 100% solventless
  • Will not cure in the presence of moisture or air
  • Fast set and cure during fastening application
  • For securing and fastening of metal screws.
  • Prevent bolts and nuts from dislodging during machine operation.
  • Secure and bond shaft in bearing.

Generally, most of the anaerobic adheisves can withstand between -40 to 150 but it also depends the chemistry and types of anaerobic adhesives being selected.
