ISO 9001:2008 CERTIFIED
T h e Q u a l i t y M a n a g e m e n t
Systems at every AOC manufacturing
facility have been certified as meeting ISO
9001:2008 tandards. This certification
recognizes that each AOC facility has an
i n t e r n a t i o n a l l y a c c e p t e d
model in place for managing and
assuring quality. We follow the
practices set forth in this model to add
value to the resins we make for our
customers.
FOOTNOTES
(1)
Based on tests at 77 F/25 C and 50% relative
humidity. All tests performed on unreinforced
cured resin castings. Thixotropic components,
if applicable, are excluded from casting samples.
Castings prepared using 1.25% M-50, 0.25%
Cobalt 6% and post cured for 5 hours at 100 C.
(2)
The gel times shown are typical but
may be affected by catalyst, promoter and
inhibitor concentrations and resin, mold
and shop temperature. Variations in gelling
characteristics can be expected between
different lots of catalysts and at extremely
high humidities. Pigment and fillers can
r e t a r d o r a c c e l e r a t e g e l a t i o n . I t i s
recommended that the fabricator check the
gelling characteristics of a small quantity
of resin under actual operating conditions prior
to use.
PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% (1.25% minimum
with mechanical application) of the total
resin weight.
B. Maintaining shop temperatures
between 65 F/18 C and 90 F/32 C and
humidity between 40% and 90% will
help the fabricator make a high
quality part. Consistent shop conditions
contribute to consistent gel times.
STORAGE STABILITY
Resins are stable for three months from
date of production when stored in the
original containers away from sunlight
at no more than 70 F/21 C.
During the hot summer months, no more
than two months stability at 86 F/30 C
should be anticipated.
After extended storage, some drift may
occur in gel time.
SAFETY

Sheet for guidelines.
