High Strength Threadlocker

Description

Fasto LockSeal HS is high strength, anaerobic thread locker & sealant. LockSeal HS cures when confined in the absence of air on close-fitting metal surfaces. LockSeal HS is slightly oil tolerant, so it will bond some ‘as received' parts, but best results are obtained with clean substrates. LockSeal HS to be used for locking & sealing where high strength opening is required. LockSeal HS prevents corrosion of assembled parts.TYPICAL APPLICATIONSFasto LockSeal HS is suitable for most medium and coarse threads. Fasto LockSeal HS is formulated to lock & seal all metric and imperial nuts and bolts, preventing vibration loosening and leakage through the threads. LockSeal HS is typically used in crushers, diesel generators, agricultural machines, Hydraulic assemblies, heavy engineering machineries and many more industrial & automobile assemblies.TYPICAL APPLICATIONSFasto LockSeal HS is suitable for most medium and coarse threads.

Lower temperatures will result in slower cure. Heating the assembled part accelerates the curing process. Activator Fasto AP49 should be used when the temperature is less than 5°C. Cure speed vs. bond gap The size of the bond gap greatly affects the speed of cure of anaerobic adhesives. Bond gap varies with thread type and size of the fastener. The larger the gap between surfaces, the slower the cure speed. Maximum recommended gap for Fasto LockSeal HS is 0.15mm. Cure speed vs. Substrate Cure speed and strength vary according to the substrates. When used on mild steel and brass components Fasto LockSeal HS will reach full strength more rapidly than on more inert materials such as stainless steel and zinc dichromate. Anaerobic Adhesives only cure in the absence of air with metal part activation. Cure speed vs. Activator Where speed is too slow or the bond gap is very large, Fasto AP49 Activator may be used to accelerate cure speed. The use of an accelerator may reduce bond strength up to 30%. Fasto recommends testing on the parts of measure the effect. TYPICAL ENVIRONMENTAL RESISTANCE Hot strength Fasto LockSeal HS is suitable for use at temperatures up to 150°C. At 150°C the bond strength will be ~45% of the strength of at 21°C.Heat ageingFasto LockSeal HS retains over 90% full strength when heated to 100°C for 90 days then cooled and tested at 21°C. Chemical / Solvent Resistance Fasto LockSeal HS exhibit excellent chemical resistance to most oils and solvents including motor oil, leaded petrol, brake fluid, acetone, ethanol, propanol and water. Anaerobic adhesives and sealants are not recommended for use in pure oxygen and chlorine lines .
