PRODUCT DESCRIPTION
Loctite Hysol 3430 is a two component epoxy adhesive which
cures rapidly at room temperature after mixing. It is a general
purpose adhesive which develops high strength on a wide
range of substrates.
TYPICAL APPLICATIONS
The gap filling properties make this adhesive system suitable
for rough or poorly fitting surfaces made from metal, ceramic,
rigid plastics or wood.

TYPICAL CURING PERFORMANCE
Cure Speed vs. time/temperature
Hysol 3430 develops high strength at room temperature within 2
to 4 hours. The assembled parts will be fixtured for light
handling (0.1N/mm²) after 12 minutes at @ 22°C in a 0.05mm
gap. Elevated temperatures may be used to accelerate the
cure. The following graph indicates development of shear
strength on a steel lap shear with 0.05mm gap as a function of
time and temperature, tested according to ASTM D-1002/EN
1465.
