CURING
CHARACTERISTICS |
| |
Stickfast 321 is cured by free radical
initiating catalysis with suitable
accelerators to promote rapid and
complete curing.

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.
