T h e Q u a l i t y M a n a g e m e n t
Systems at every AOC manufacturing
facility have been certified as meeting ISO
9001:2008 tandards. This certification
recognizes that each AOC facility has an
i n t e r n a t i o n a l l y a c c e p t e d
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 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 prepared using 1.25% M-50, 0.25%
Cobalt 6% and post cured for 5 hours at 100 C.
(2)
The gel times shown are typical but
may be affected by catalyst, promoter and
inhibitor concentrations and resin, mold
and shop temperature. Variations in gelling
characteristics can be expected between
different lots of catalysts and at extremely
high humidities. Pigment and fillers can
r e t a r d o r a c c e l e r a t e g e l a t i o n . I t i s
recommended that the fabricator check the
gelling characteristics of a small quantity
of resin under actual operating conditions prior
to use.
PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% (1.25% minimum
with mechanical application) of the total
resin weight.
B. Maintaining 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.
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.
SAFETY

Sheet for guidelines.

PERFORMANCE GUID ELINES
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.
SAFETY
See the appropriate Safety Data Sheet
for guidelines.

FOOTNOTES
(1.) Based on tests at 77 F/25 C and 50% relative

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.

HYDROPEL
R010-FPA SERIES VINYL ESTER RESIN
PERFORMANCE GUID ELINES
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.
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 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 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.

Styrosafe is extremely flammable. Do not apply near sparks, open flames or heat.
Keep area v entilated. Do not smoke. Avoid continuous breathing of vapor.
Styrosafe contains ingredients which could be harmful if mishandled. Contact with
skin and eyes should be
avoided and necessary protective equipment and clothing
s
hould be worn. Individuals should was h with soap and water before eating or
drinking. All containers s
hould be properly labeled to prevent accidental ingestion
or improper disposal. I

DESCRIPTION
Designed specifically for use on expanded polystyrene
foam. This
special polyester resin does not chemically attack EPS foam, but bonds,
and creates a barrier. Once cured, Styrosafe protects EPS foam from
chemical attack from general purpose unsaturated polyester resins or
styrene-containing coatings allowing low cost EPS foam to be
substituted for expensive urethane tooling board or MDF.

Use Instructions
Although StyroSafe Laminating Resin #30P-106A is compatible with low density polystyrene
foam, there are some precautions to follow when using the product:
Do not leave a puddle of resin on the foam after laminating onto the surface as some
chemical attack can occur due to excess exotherm development.
After the first, or skin coat, laminate has been applied, wait until it exotherms and
cools before following with the next laminates. Too much exothermic heat will melt the foam.
(1) Styrosafe needs to be catalyzed using an MEKP catalyst. We have used both Cadox L50 and
Norox 925 successfully in our testing and trials. Catalyze at 1.5% by weight.
(2) Apply at least two laminates made with StyroSafe resin before switching to a GP resin system
as the two laminates will insure that there will be no chemical attack of the foam.
NOTE: based on industry information about Expanded Polystyrene Foam we do not
recommend that the foam be subject to vacuum or temperatures above 160 F.
XPS FOAM OPTION: We are frequently asked whether StyroSafe can be used in conjunction
with XPS foam. StyroSafe was designed for best results with the cell structure of EPS foam – the
functionality and cell structure of XPS foam is functionally different. If you are working with
XPS foam, we advocate testing to your process to determine compatibility.
