PRODUCT DESCRIPTION
LOCTITE
LOCTITE
threaded fasteners which require easy disassembly with
standard hand tools. The product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration.
Particularly suitable for applications such as adjustment of
set screws, small diameter or long engagement length
fasteners, where easy disassembly is required without
shearing the screw. The thixotropic nature of LOCTITE
reduces the migration of liquid product after application to the
substrate.

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph
below shows the breakaway strength developed with time on
M10 steel nuts and bolts compared to different materials and
tested according to ISO 10964.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Gaps in
threaded fasteners depends on thread type, quality and size.
The following graph shows shear strength developed with time
on steel pins and collars at different controlled gaps and tested
according to ISO 10123.
Cure Speed vs. Temperature
The rate of cure will depend on the temperature. The graph
below shows the breakaway strength developed with time at
different temperatures on M10 steel nuts and bolts and tested
according to ISO 10964.
Cure Speed vs. Activator
Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows the breakaway strength
developed with time on M10 zinc dichromate steel nuts and
bolts using Activator 7471™ and 7649™ and tested according
to ISO 10964.
