Not Good For
Don't Use For piping systems that contain pure oxygen or oxygen-rich environment, chlorine, or strong oxidizing substances. Don't Use With most plastics due to potential cracking of plastic parts.
Best Practices for 3M Rite-Lok Pipe Sealant PS65
Ensure parts are clean, dry and free from oil, grease and dirt. For best results, clean and dry parts with solvent or a 3M™ Scotch-Weld™Anaerobic Activator. (Activator can also be used on inactive surfaces or to accelerate the cure on active surfaces.)
Note: Use of a 3M™ Scotch-Weld™ Activator with 3M™ Scotch-Weld™ Pipe Sealant Anaerobic Adhesives may reduce bond strength depending on substrates and gap. Testing is recommended to evaluate the effect.
If not sure of surface type, always use activator
Apply sealant onto the second and third threads (not the first thread) of the male fitting so as to avoid introducing uncured sealant into the system. (However, should uncured sealant get into the piping system, it will not cure or cause blockage and can be flushed out.)
Avoid touching the metal surfaces with the bottle tip since the metal ions may react with the adhesive upon contact and eventually may clog the bottle tip.
Spread adhesive evenly around the male fitting.
Assemble parts and tighten as required.
Allow assemblies to set for sufficient time so that handling strength or full cure will occur before further processing or testing.
