LOCTITE® Product 635 is a high strength, high viscosity, singlecomponent anaerobic retaining adhesive for cylindrical joints. The product cures when confined in the absence of air between
TYPICAL APPLICATIONS Used to bond cylindrical fitting parts. Typical applications
include rotor to shafts in fractional and subfractional horsepowermotors. Locks bearings in place, preventing spin out. Locks
bushings and sleeves in housings on shafts. Augments press
% of Full Strength on Steel Cure Time, Hours PROPERTIES OF UNCURED MATERIAL Cure speed vs. primer
Where cure speed is unacceptably long, or large gaps are
present, applying activator to the surface will improve cure
speed. The graph below shows shear strength developed with
time using Primer N and T on zinc dichromated steel pins and
collars and tested according to ISO-10123. TYPICAL CURING PERFORMANCE Cure speed vs. substrate
The rate of cure will depend on substrate used. The graphbelow shows shear strength developed with time on steel pins
and collars compared to different materials and tested according

Where aqueous washing systems are used to clean thesurfaces before bonding, it is important to check for compatibility
of the washing solution with the adhesive. In some cases these
aqueous washes can affect the cure and performance of the
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of the
plastic could result). It is recommended to confirm thecompatibility of the product with such substrates. Directions for use
For best performance surfaces should be clean and free ofgrease. Ensure joint is completely filled with adhesive. For slip
fitted assemblies this is achieved by applying adhesive aroundthe pin and the leading edge of the collar and using a rotating
motion during assembly to ensure good coverage. For pressfitted assemblies adhesive should be applied thoroughly to both

bond surfaces and assembled at high press on rates. For shrinkfitted assemblies the adhesive should be coated onto the pin,
the collar should then be heated to create sufficient clearance
for free assembly. Parts should not be disturbed until sufficienthandling strength is achieved. This grade will developtemperature resistance after exposure to a heat cure of one
