Service Temperature Range -50 to +150C Scotch-Weld Anaerobic Threadlocker TL70 February 2010 Additional Product Anaerobic adhesives only cure in the absence of air and with metal part Information activation. Adhesive outside the joint will remain uncured and may be wiped away with a cloth. Scotch-Weld TL70 is suitable for most standard diameter, medium to coarse- threaded screws, nuts and bolts. Not recommended on certain plastics as stress cracking can sometimes result. Some anti-corrosion chemicals inhibit the cure system in this type of anaerobic. Trials are recommended to establish whether cleaning of the parts is necessary. Scotch-Weld AC64 Activator may be required on plated parts. Application Ensure parts are clean, dry and free from oil and grease. Techniques Apply adhesive to all engaged threads. Assemble parts and allow to cure. Wipe excess adhesive from outside of joint. Heating the assembled parts accelerates the curing process. Scotch-Weld AC64 Activator may be used to accelerate cure and should be used if the application temperature is below 5C. The use of an accelerator may reduce the final bond strength by up to 30% Storage Conditions Keep the adhesive in a cool, dry place away from direct sunlight.
