3M TL72 Rite-Lok Threadlocker

Surface Preparation

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

For best results, clean and dry parts with solvent or 3M™ 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.

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.

Curing

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