DESCRIPTION
AOC’s Vipel K022 series are brominated bi-
sphenol-A epoxy vinyl ester resins dissolved in
styrene.
APPLICATION
Vipel K022 series is ideally suited for use in
hand lay-up, spray-up, filament winding and
pultrusion processes where outstanding me-
chanical properties and excellent resistance to
chemicals and heat are required.
All versions of the K022 Series do not meet
ASTM E84 Class 1 smoke requirements.
BENEFITS
Versatile
Vipel K022 is available in a wide range of for-
mulations, which allows the product to be used
in many processes and also optimizes
cost/performance.
Vipel K022-CN versions already contain an
antimony product to meet a Class 1 flame
spread.
Fire Retardant
Because of the versatility of Vipel K022, ver-
sions are available to meet ASTM E 84 Class 1
or 2 flame spread.
Mechanical Properties
Vipel K022 is suitable for moldings that are
subjected to particularly high static or dynamic
loads.
Corrosion Resistance
Vipel K022 is highly resistant to a number of
chemical environments. Refer to AOC’s
“Corrosion Resistant Resin Guide” for corrosion
resistance information or for questions regard-
ing suitability of a resin to any particular chemi-
cal environment contact AOC.
Vipel K022-CN versions are not recommended
for use in the corrosion liner.

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 GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.5% 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 con-
sistent gel times and will help the
fabricator make a high quality part.
C. Finished part surfaces that have
been cured at room temperature in
contact with air should be relatively
tack free. They may not, however,
be fully cured and are thus not as
resistant to chemicals as a fully
cured part. If no further laminating
is planned, a 10% solution of 5%
paraffin wax solution (MP
115-118 F/46-48 C) in styrene
may be added to the last resin layer
to provide a tack free surface.
D. Optimum cure and performance
may be obtained by post curing
room temperature cured laminates
for two hours at 158-212 F/70-
100 C.
E. Room temperature curing by
means of cobalt acceleration
should be completed with low hy-
drogen peroxide content MEKP cat-
alyst, such as MEKP 925H, to mini-
mize foaming.
STORAGE STABILITY
Vipel K022-ACP-20, K022-ACT-30,
K022-ACT-45, K022-CCK-18, K022-
CNP-25 and K022-EAA-40 are sta-
ble for 3 months from the date of
manufacture when stored in origi-
nal containers, away from direct
sunlight or other UV light sources
and at or below 77 F (25 C). All
other Vipel K022 products are sta-
ble for 6 months from the date of
manufacture when stored in origi-
nal containers, away from direct
sunlight or other UV light sources
and at or below 77 F (25 C).
Storage stability of two months or
less should be anticipated if the
storage temperature exceeds 86 F
(30 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 9001:2015 CERTIFIED
The Quality Management Systems
at every AOC manufacturing facility
have been certified as meeting ISO
9001:2015 standards. This certifi-
cation recognizes that each AOC
facility has an internationally ac-
cepted 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
unreinforced cured resin castings. Thixotropic com-
ponents, if applicable, are excluded from casting
samples. Castings were prepared using 1.0% BPO
and post cured 1 hour at 93 C, 1 hour at 116 C
and 2 hours at 138 C.
(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 fillers can retard or accel-
erate gelation. It is recommended that the fabrica-
tor check the gelling characteristics of a small quan-
tity of resin under actual operating conditions prior
to use.
