DESCRIPTION
Altek H834-R Series is a medium re-
active, thixotropic, pre-promoted res-
in.

APPLICATION
The Altek H834-R Series was de-
signed for use in the manufacturing
of boats and other composite parts
using hand lay-up or spray-up applica-
tion methods.

BENEFITS
Fast laminate cure rate allows for
faster production rates without loss
of surface profile

Reduced post cure

Fast and complete fiber wet-out

Good resistance to osmotic blister-
ing (for improved blister resistance,
a skin coat made with Hydropel
H034-A can be used)

Will provide good physical proper-
ties in finished part

Adaptable to a variety of manufac-
turing processes and conditions

Meets requirements for low styrene
resins in the marine industry

ALTEK

H834-R SERIES POLYESTER RESIN
PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.25% – 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%
and 90% will help the fabricator
make a high quality part. Consistent
shop conditions contribute to con-
sistent gel times viscosity.

C. Sanding and/or grinding is recom-
mended if a secondary bond is ap-
plied 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 contain-
ers, away from direct sunlight or oth-
er UVA light sources and at or below
77 F/25 C.

Storage stability of two months or
less should be anticipated if the stor-
age temperature exceeds
86 F/30 C.

After extended storage, some drift
may occur in the product viscosity
and gel time.
APPLICATION GUIDELINES
Due to the excellent curing character-
istics of Altek H834-R Series resin,
complete all secondary bonding as
soon as possible. Exposing the lami-
nate to sunlight will result in severe
secondary bonding problems. After
24 hours of cure, it may be necessary
to abrade the laminate to insure good
secondary bonding, especially if the
surface of the laminate is resin rich.
Avoid low fiberglass content and res-
in puddling 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 H834-R Series have
every poor resistance to certain hy-
drophobic liquids such as hydrocar-
bons. Fuel storage tanks should not
be produced with H834-R Series res-
ins.

If your manufacturing needs re-
quire a more corrosion resistant res-
in, please contact your AOC repre-
sentative for information or technical
assistance on AOC’s line of isophthal-
ic or vinyl ester resins.

SAFETY
See the appropriate Safety Data
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 run at 77 F/25 C and 50%
relative humidity. All tests performed on unrein-
forced cured resin castings. Thixotropic compo-
nents, 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.
