* None of the K022 products meet ASTM E 84 Class 1 smoke requirements, which is defined as less than 450. Consult an AOC representa-
tive for specific smoke development value.
Panels were post cured at 212 F/100 C for 3 hours.
Note: The degree of fire resistance of a cured resin is characterized by the ASTM E 84 test. This test is performed under strictly controlled
conditions where a flame spread rating is assigned according to comparisons with test set-point materials. The behavior of the end-users
composite cured under controlled conditions can vary significantly in an actual fire situation due to the large number of unpredictable varia-
bles associated with actual fire situations.

PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total resin
weight.
B. Maintaining shop temperatures be-
tween 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 condi-
tions contribute to consistent gel times
and will help the fabricator make a
high quality part.
C. Optimum cure and performance
may be obtained by post curing room
temperature cured laminates for two
hours at 158-212 F/70-100 C.
D. Room temperature curing by
means of cobalt acceleration should
be completed with low hydrogen
peroxide content MEKP catalyst, such
as MEKP 925H, to minimize foaming.
STORAGE STABILITY
The Vipel K022-INA-20 Series is stable
for three months from the date of
manufacture when stored in the origi-
nal containers, away from direct sun-
light or other UV light sources and at
or below 25 C (77 F). The Vipel
K022-INA-00 product is stable for 6
months from the date of manufacture
when stored in original containers,
away from direct sunlight or other UV
light sources, and at or below 25 C
(77 F).
Storage stability of two months or less
should be anticipated if the storage
temperature exceeds 30 C (86 F).
After extended storage, some drift may
occur in the product viscosity and gel
time.
SAFETY
See the appropriate Safety Data Sheet
for guidelines.
ISO 9001:2015 CERTIFIED
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2015 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 of Vipel K022 at 77 F/25 C and
50% relative humidity. All tests performed on unrein-
forced cured resin castings. Thixotropic components, if
applicable, are excluded from casting samples. Cast-
ings were prepared using 1.0% BPO and post cured 2
hours at 138 C.
(2.) The gel times shown are typical but may be affect-
ed by catalyst, promoter, inhibitor concentration, resin,
mold, and shop temperature. Variations in gelling char-
acteristics can be expected between different lots of
catalysts and at extremely high humidities. Pigment
and fillers can retard or accelerate gelation. It is recom-
mended that the fabricator check the gelling character-
istics of a small quantity of resin under actual operating
conditions prior to use.
