LOCTITE

609 is designed for the bonding of cylindrical fitting
parts. 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 rotor to shafts in fractional and subfractional
horsepower motors. Locks bushings and sleeves in housings
on shafts. Augments press fits.

609 is tested to the lot requirements of Military
Specification Mil-R-46082B.
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 CURING PERFORMANCE
Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph
below shows the shear strength developed with time on steel
pins and collars compared to different materials and tested
according to ISO 10123.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. 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 shear strength developed with time at
different temperatures on steel pins and collars and tested
according to ISO 10123.

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 shear strength developed with
time using Activator 7471 and 7649 on zinc dichromate steel
pins and collars and tested according to ISO 10123.
