DESCRIPTION
AOC’s Hydropel H034-A Series is a
thixotropic, pre-promoted, modified
vinyl ester resin.
APPLICATION
AOC’s Hydropel H034-A Series is de-
signed for use in the manufacturing
of boats or other composite parts us-
ing hand lay-up or spray-up applica-
tion methods. For boat fabrication,
Hydropel H034-A Series can be used
either in a skin coat or for the com-
plete laminate to obtain the maxi-
mum benefits
BENEFITS
Good resistance to osmotic blis-
tering when used for the skin coat
or the complete composite.
Excellent strength and toughness
of the finished composite part.
Provides improved resistance to
cracking caused by the flexural
failure of the laminate even when
used only for the skin coat.
Good surface profile, with reduced
post cure on finished parts.
Meets MACT requirements for low
HAP resins in the marine industry.

H034-A SERIES VINYL ESTER RESIN
PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total res-
in 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 contrib-
ute to consistent gel times and will
help the fabricator make a high quali-
ty part.
STORAGE STABILITY
Resins are stable for three months
from date of production when stored
in the original containers away from
sunlight at no more than 70 F/21 C.
During the hot summer months, no
more than two months stability at
86 F/30 C should be anticipated.
After extended storage, some drift may
occur in gel time and viscosity.
Storage in plastic totes made out of
materials such as polyethylene (PE) or
polypropylene (PP), in particular trans-
lucent PE/PP, will accelerate gel for-
mation and result in a significantly re-
duced storage stability.
Storage of this resin outdoors in
translucent plastic totes may reduce
the storage stability to only a few
weeks. AOC cannot assume responsi-
bility for gel formation under these
storage conditions.
APPLICATION GUIDELINES
Due to the curing characteristics of
the Hydropel H034-A Series resin, it
is desirable to complete all secondary
bonding as soon as possible. Expo-
sure of the laminate to the sunlight
will result in severe bonding prob-
lems. After 24 hours of cure, it may
become necessary to abrade the lam-
inate to insure good secondary bond-
ing, especially if the surface of the
laminate has been allowed to be-
come resin rich. Low fiberglass con-
tent and resin puddling should be
avoided with this product.
To assure adequate bonding to gel
coats, fabricators should pre-wet the
gel coat surface with a thin pass of
catalyzed resin prior to lamination.
Chemical resistance studies indicate
that resins like Hydropel H034-A Se-
ries have poor resistance to certain
hydrophobic liquids, such as hydro-
carbons. Fuels storage tanks should
not be produced with the Hydropel
H034-A Series resin.
If your manufacturing needs require a
more corrosion resistant resin,
please contact your AOC representa-
tive for information or technical assis-
tance on AOC’s line of isophthalic or
vinyl ester resins.
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 mod-
el 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 are post cured.
(2.) The gel times shown are typical but may be
affected by catalyst, promoter, inhibitor concen-
tration, resin, mold, and shop temperature. Varia-
tions in gelling characteristics can be expected
between different lots of catalysts and at ex-
tremely high humidities. Pigment and/or filler can
retard or accelerate gelation. It is recommended
that the fabricator check the gelling characteris-
tics of a small quantity of resin under actual
operating conditions prior to use.
