PERFORMANCE GUID ELINES
A. Keep full strength catalyst lev-
els between 1.0% – 2.0% of the to-
tal resin weight.
B. Maintain shop temperatures be-
tween 65 F/18 C and 90 F/32 C
and humidity between 40% and
90%. Consistent shop conditions
contribute to consistent gel time
and will help the fabricator make a
high quality part.
C. Sanding and/or grinding is rec-
ommended if a secondary bond is
applied to a laminate that was
made with a resin containing wax.
STORAGE STABILITY
This product is stable for three
months from the date of manufac-
ture when stored in the original con-
tainers, away from direct sunlight or
other UV light sources and at or be-
low 77 F/25 C.
After extended storage, some drift
may occur in the product viscosity
and gel time.
SAFETY
See the appropriate Safety Data Sheet
for guidelines.
ISO 9001:2008 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2008 standards. This certifica-
tion recognizes that each AOC facility
has an internationally accepted 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% rela-
tive humidity. All tests performed on unreinforced
cured resin castings. Thixotropic components, if
applicable, are excluded from casting samples.
Castings were post cured.
(2.) The gel times shown are typical but may be
affected by catalyst, promoter, inhibitor concentra-
tion, resin, mold, and shop temperature. Variations
in gelling characteristics can be expected between
different lots of catalysts and at extremely high
humidities. Pigment and/or filler can retard or
accelerate gelation. It is recommended that the
fabricator check the gelling characteristics of a
small quantity of resin under actual operating
conditions prior to use.
