PRODUCT DESCRIPTION
Loctite Hysol 3450 is a two component epoxy adhesive which
cures rapidly at room temperature after mixing. It is a metal
bonding adhesive which develops high strength.
TYPICAL APPLICATIONS
The gap filling properties make this adhesive system suitable
for rough or poorly fitting surfaces made from metal, ceramic,
wood or rigid plastics. Applications include bonding aluminium
window frames and GRP panels.

TYPICAL CURING PERFORMANCE
Cure Speed vs. time/temperature
When mixed in a 1:1 ratio by volume Hysol 3450 develops high
strength at room temperature within 1 hour. Elevated
temperatures may be used to accelerate the cure. The
following graph indicates development of shear strength on
steel lap shear as a function of time and temperature.
