Performance Guidelines
A. Keep full strength catalyst levels
between 1.25% – 2.0% of the total for-
mulation 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.

Storage Guidelines
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 translu-
cent PE/PP, will accelerate gel formation
and result in a significantly reduced stor-
age stability.

Storage of this formulation 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 H125-A Series formulation, it
is desirable to complete all secondary
bonding as soon as possible. Exposure
of the laminate to sunlight will result in
severe secondary bonding problems.
After 24 hours of cure, it may become
necessary to abrade the laminate to
insure good secondary bonding, espe-
cially if the surface of the laminate has
been allowed to become resin rich.
Low fiberglass content and resin pud-
dling should be avoided with this
product.

To assure adequate bonding to acryl-
ics, fabricators should pre-wet the
acrylic surface with a thin pass of cata-
lyzed resin prior to lamination.

The ability of an unsaturated polyester
resin to bond to acrylic is influenced
by many factors. Resin is only one of
the factors. The type and color of the
acrylic used and the conditions during
the thermoforming process are but a
few of the factors that affect the ability
of the resin to bond to the acrylic.
Therefore, it is vitally important that
the fabricator evaluates for themselves
the fitness of this product for their
processes.

To ensure a high quality fabricated
part, AOC recommends that fabrica-
tors utilize Best Practice Guidelines
for polyester resins, vinyl ester resins,
acrylic sheet.
ISO 9001:2015 Certified
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2015 standards. 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 products we
make for our customers.

Material Safety
See the appropriate Safety Data Sheet
for guidelines.

Test Methods

(1.) Based on tests at 77 F/25 C and 50% relative
humidity. All tests performed on unreinforced
cured resin castings. Thixotropic components, if
applicable, are excluded from casting samples.
Castings were 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 oper-
ating conditions prior to use.

Performance Guidelines
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total
resin weight.

B. Maintain 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 consistent gel times
viscosity.

Storage Guidelines
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.

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 trans-
lucent plastic totes may reduce the
storage stability to only a few weeks.
AOC cannot assume responsibility for
gel formation under these storage
conditions.
Application Guidelines
Due to the excellent curing character-
istics of Altek H800-TVA-18 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 resin
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 dicyclopentadiene resins such as
Altek H800-TVA-18 have very poor
resistance to certain hydrophobic liq-
uids, such as hydrocarbons. Fuel stor-
age tanks should not be produced
with the Altek H800-TVA-18 resin.

If your manufacturing needs require a
more corrosion resistant resin, please
contact your AOC representative for
information for technical assistance on
AOC s line of isophthalic or vinyl ester
resins.
ISO 9001:2015 Certified
The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2015 standards. This certification
recognizes that each AOC facility has
an internationally accepted model in
place for managing and assuring qual-
ity. We follow the practices set forth in
this model to add value to the resins
we make for our customers.

Material Safety
See the appropriate Safety Data Sheet
for guidelines.

Test Methods

(1.) Based on tests at 77 F/25 C and 50% relative
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. Vari-
ations 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 recom-
mended that the fabricator check the gelling
characteristics of a small quantity of resin under
actual operating conditions prior to use.

ed 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.

Due to the excellent curing character-
istics of the Altek C431-PPC-18 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 resin
puddling with this product.

Caution:
The ability of an unsaturated polyester
resin to bond to acrylic is influenced by
many factors. Resin is only one of
these factors. The type and amount of
filler used, type and color of acrylic
used, and the conditions during the
thermoforming process are but a few
of the factors that effect the ability of
the resin to bond to the acrylic. There-
fore, it is vitally important that the fab-
ricators evaluate for themselves the
fitness of this product for their pro-
cess.

To insure high quality fabricated parts,
AOC strongly encourages fabricators to
utilize “Best Practices Guidelines” for
polyester resin, ABS and acrylic sheet.

SAFETY
See the appropriate Safety Data Sheet
for guidelines.

The Quality Management Systems at
every AOC manufacturing facility have
been certified as meeting ISO
9001:2015 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

FOOTNOTES

(1.) Based on tests of at 77 F/25 C and 50%
relative humidity. All tests performed on unrein-
forced cured resin castings. Castings were post
cured.
(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/or filler can retard or
accelerate gelation. It is recommended that the
fabricator check the gelling characteristics of a
small quantity of resin under actual operating
conditions prior to use.
