CURING
CHARACTERISTICS |
| |
Stickfast 313 is cured by free
radical initiating catalysis
with suitable accelerators to
promote rapid and complete curing.
Typical
gelation at 25 °C
for Stickfast 313 is as followed:

CAUTION : Accelerator should
never be mixed with catalyst
as this would cause explosion,
the accelerator should be blended
into the resin first. The catalyst
should be added just before
use. |

| POST
CURING REQUIREMENTS |
| |
| Satisfactory
laminates for many applications
can be made by curing
the laminate at ambient
temperatures. However
for achieving optimum
properties the laminate
should be post cured for
a period of 4 hours at
80°C.
The Post curing is most
effective when carried
out immediately after
the 24 hours ambient temperature
cure. |
