3M Scotch-Weld Threadlocker TL43

3M Scotch-Weld Threadlocker TL43 Datasheet
  • Description for 3M Scotch-Weld Threadlocker TL43

    A one component anaerobic adhesive that cure and seal threaded assemblies is a general purpose, removable with hand tools, medium strength threadlocker for most medium and coarse-threaded screws, nuts and bolts. It is oil tolerant to help secure as-received parts and its thixotropic property prevents run-off, dripping, or migration of the adhesive product when applied on parts.

  • Best Practices for 3M Scotch-Weld Threadlocker TL43

    *See Terms of Use Below

    1. Surface Preparation

      Ensure parts are clean, dry and free from oil, grease and dirt.

      For best results, clean and dry parts with solvent or Scotch-Weld™ Activator. (Activator can also be used on inactive surfaces or to accelerate the cure on active surfaces.)

      If not sure of surface type, always use activator.

    2. Application

      Shake the adhesive bottle well before use.

      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.

      Apply adhesive onto the threaded part where the contact area will be in the final assembly. For larger parts, use more adhesive and rotate the threaded part to spread adhesive evenly around contact area.

      For through holes, apply several drops of adhesive onto the bolt at the nut engagement area. For blind holes, apply several drops of the adhesive down the internal threads to the bottom of the hole.

    3. Curing

      Allow assemblies to set for sufficient time so that handling strength or full cure will occur before further processing or testing.
