DESCRIPTION
AOC s Vipel F085 series is an epoxy
novolac vinyl ester resin dissolved in
styrene.
APPLICATION
The Vipel F085 series is ideally suited
for applications where outstanding me-
chanical properties and resistance to
chemicals, oxidation and heat are re-
quired.
BENEFITS
Corrosion Resistant
Vipel F085 offers excellent resistance
to acidic and mild alkaline environ-
ments. Performs well in a wide range
of acidic oxidants and solvents. Vipel
F085 is generally resistant to liquids
and vapors at higher temperatures
than standard bisphenol-A epoxy vinyl
ester resins.
The Vipel F085 series is well suited for
use in the field of chlorine-alkali elec-
trolysis. Refer to AOC’s “Corrosion Re-
sistant Resin Guide” for corrosion re-
sistance information or for questions
regarding suitability of a resin to any
particular chemical environment, con-
tact AOC.
Mechanical Properties
Vipel F085 series is suitable for mold-
ings that are subjected to particularly
high static and dynamic loads. It is re-
sistant to internal stress cracking un-
der high loading.
Versatile
Suitable for various fabricating meth-
ods such as hand lay-up, filament
winding, etc.

PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels be-
tween 1.0% – 2.0% of the total resin
weight.
B. Maintain shop temperatures be-
tween 65 F/18 C and 90 F/32 C and
humidity between 40% and 90%. Con-
sistent shop conditions contribute to
consistent 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 re-
sistant to chemicals as a fully cured
part. If no further laminating is planned,
a 10% solution of 5% paraffin wax solu-
tion (MP 115-118 F/46-48 C) in sty-
rene 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 tem-
perature cured laminates for two hours
at 158-212 F/70-100 C.
STORAGE STABILITY
This product is stable for seven months
from the date of manufacture when
stored in the original containers, away
from direct sunlight or other UV light
sources and at or below 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 stand-
ards. This certification 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 F085-AAA-00 at 77 F/25 C.
and 50% relative humidity. All thixotropic resins should
be mixed well prior to use. All tests on unreinforced
cured resin. Castings were prepared using 1% BPO and
post cured 1 hour at 82 C, 1 hour at 93 C, 1 hour at
116 C, 1 hour at 138 C and 5 hours at 166 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/or filler can retard or accelerate gelation. It is rec-
ommended that the fabricator check the gelling charac-
teristics of a small quantity of resin under actual operat-
ing conditions prior to use.
