DESCRIPTION
AOC’s Vipel F737-P series is a resilient
isophthalic polyester resin with excel-
lent mechanical properties. Vipel F737-
P resins are used extensively in grating
and in the construction of large diame-
ter water pipes for transporting water
to and from power stations. Vipel F737-
P resins can be adapted for a variety of
fabrication processes.
BENEFITS
Internationally Recognized
AOC’s Vipel F737-P series resins have
been used in many corrosion resistant
applications such as grating and water
pipes, etc.
Corrosion Resistance
This resin provides excellent corrosion
resistance when used in contact with in-
organic and organic acids. Refer to AOC’s
“Corrosion Resistant Resin Guide” for
corrosion resistance information or for
questions regarding suitability of a resin
to any particular chemical environment
contact AOC.
Versatile
Suitable for various fabricating methods
such as hand lay-up, spray-up, filament
winding, etc.
Food and Drug
All resins in this datasheet are manufac-
tured from raw materials that are listed
in FDA regulation Title 21 CFR 177.2420.
It is the fabricator’s responsibility to also
be sure that the final composite is well
cured. All composites used for FDA appli-
cations should e post cured at
180 F/82 C for at least 4 hours. After
post curing, laminate should be washed
with soap and water and rinsed.

POLYESTER RESIN
PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 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%.
Consistent shop conditions contribute
to consistent gel times and will help
the fabricator make a high quality part.
C. Sanding and/or grinding is recom-
mended 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 manufacture when
stored in the original 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.
Storage in plastic totes made out of
materials such as polyethylene (PE) or
polypropylene (PP) in particular trans-
lucent PE/PP will accelerate gel forma-
tion and result in a significantly re-
duced storage stability.
Storage of this resin outdoors in trans-
lucent plastic totes may reduce the
storage stability to only a few weeks.
AOC cannot assume responsibility for
gel formation under these storage con-
ditions.
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 of the base resin with 40% styrene
at 77 F/25 C and 50% relative humidity. All tests
performed on unreinforced cured resin castings. Thixo-
tropic components, if applicable, are excluded from
casting samples. Castings were prepared using 1%
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 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.
