PRODUCT DESCRIPTION
LOCTITE
LOCTITE
sealing of threaded fasteners. The product cures when
confined in the absence of air between close fitting metal
surfaces and prevents loosening and leakage from shock and
vibration. Typical applications include the locking and sealing
of large bolts and studs (M25 and larger). The thixotropic
nature of LOCTITE
product after application to the substrate.
Mil-S-46163A
LOCTITE
Specification Mil-S-46163A.
ASTM D5363
Each lot of adhesive produced in North America is tested to
the general requirements defined in paragraphs 5.1.1 and
5.1.2 and to the Detail Requirements defined in section 5.2
TYPICAL PROPERTIES OF UNCURED MATERIAL
TYPICAL CURING PERFORMANCE
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.
