flexibility and peel strength along with enhanced resistance to
shock.
TYPICAL PROPERTIES OF UNCURED MATERIAL
TYPICAL CURING PERFORMANCE
Under normal conditions, the atmospheric moisture initiates the
curing process. Although full functional strength is developed
in a relatively short time, curing continues for at least 24 hours
before full chemical/solvent resistance is developed.
Cure Speed vs. Substrate
Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. Thin bond
lines result in high cure speeds, increasing the bond gap will
decrease the rate of cure.
Cure Speed vs. Activator
Where cure speed is unacceptably long due to large gaps,
applying activator to the surface will improve cure speed.
However, this can reduce ultimate strength of the bond and
therefore testing is recommended to confirm effect.

Key Substrates
The rate of cure will depend on the substrate used. The table
below shows the fixture time achieved on different materials
at 22 °C / 50 % relative humidity. This is defined as the time to
develop a shear strength of 0.1 N/mm².
