Seal instantly

Keep equipment and production up and running. When you need secure fits, 3MTM Scotch-WeldTM Anaerobic Adhesives offers a wide selection of properties to help save the time and cost of disruptive, unscheduled downtime due to leaks and loose fasteners.

For threadlocking, sealling, retaining, and gasketing, application is fast and easy with just targeted squeeze of a bottle or tube. In the absense of oxygen and in the presence of metal, the anaerobic formulation cures quickly to a polymer that seals, secures, and retains.

Prevent loosening

3MTMScotch-WeldTMThreadlockers

Apply to nuts, bolts, and screws to prevent loosening from vibration and impact in such applications as gear housings, motor mounts, and sprinkler heads.

Tighten tolerances

3MTMScotch-WeldTMRetaining Compounds

Bond and seal non-threaded, co-axial components such as bearings, gears, shafts, cylinder liners, and roters.

Fill voids

3MTMScotch-WeldTMGasket Makers

Fill and seal voids between metal flanges to eliminate pre-cut or compression gaskets.

3MTMScotch-WeldTMPipe Sealants

Seal instantly to stop leaks when applied to threads or compression fittings of most metal and certain plastic pipes. Replace traditional PTFE tapes and dope without shredding, evaporation, or shrinkage.
