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.

DESCRIPTION
MoldTru LPT-68000 is a pre-promoted thixotropic
vinyl ester low profile tooling resin. The high perfor-
mance mechanical properties of the vinyl ester res-
in provides a laminate of quality and integrity with
superior surface quality.

APPLICATION
The MoldTru LPT-68000 was developed primarily to
build molds using the conventional open mold pro-
cess (spray up or hand lay up) at a room tempera-
ture. In some cases a vacuum molding process can
be used to obtain high glass content using tech-
nical fabrics. The low viscosity of this product pro-
vides good wet out of the laminate and air removal.

BENEFITS
MoldTru LPT-68000 has several advantages when
considering the performance of the polymer and
the reaction of the low profile during the mold con-
struction. Some of the advantages are:

Dramatic build time reduction
Up to five layers can be laminated at once.

Lower labor cost
Reduce the timing between layers

No surface distortion
The low shrinkage of the product increases
the dimensional stability of the laminate.

Master molds replication
The low exotherm together with a high HDT
provide a correct cure and stability of the
laminate. The low shrinkage improves the
surface quality.

Viscosity
The low viscosity helps the infusion flow
faster and wets the high glass content
laminate complete.

No print through
Low shrinkage and unique low profile
system helps to prevent glass print.

assume any liability for occurrences arising out of its use. The user, by accepting the products described herein, agrees to be responsible for thoroughly testing each such product before committing
to production. Our recommendations should not be taken as inducements to infringe any patent or violate any law, safety code or insurance regulation. This data sheet and its contents are the
confidential and proprietary information of AOC and it may not be modified altered deconstructed or presented in any other manner without the explicit authorization of AOC and/or its legal counsel.
PERFORMANCE GUID ELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% of the total res-
in 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.

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 23 C and 50% relative
humidity. All tests performed on unreinforced
cured resin castings. 1/4″ castings were pre-
pared using 2.8% MEKP-9, post cured for 5 hours
at 212 F/100 C using AOC test method X-12Ab.

(2.) The gel times shown are typical but may be
affected by catalyst, promoter and inhibitor con-
centrations and resin, mold and shop tempera-
ture. Variations in gelling characteristics can be
expected between different lots of catalysts and
at extremely high humidities. Pigment and fillers
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.

STORAGE STABILITY
This product is stable for three
months from the date of manufac-
ture when stored in the original con-
tainers, away from direct sunlight or
other UV light sources and at or be-
low 20 C (70 F). After extended
storage, some drift may occur in the
product viscosity and gel time.

During the hot summer months, no
more than two months stability at
86 F/30 C should be anticipated.

Storage in plastic totes made out of
materials such as polyethylene (PE)
or polypropylene (PP), will accelerate
gel formation and result in a signifi-
cantly reduced 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.

FIREPEL K140 POLYESTER FIRE RETARDANT RESIN APPLICATION GUIDELINES A. Some separation of the K140 resin is normal upon standing. Mix the resin thoroughly in the original container at least 15 minutes prior to use. Firepel K140 is provided in partially filled open top containers with enough space for easy mixing with the promoters. B. Use mixing equipment with suffi- cient horsepower based on the size of the container to ensure adequate mixing. Adequate mixing is evident when the resin is homogenous and no undissolved material is present on the bottom of the container. C. To assure adequate bonding to gel coats, fabricators should pre-wet the gel coat surface with a thin pass of catalyzed resin prior to lamina- tion. 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. After extended storage, some drift may occur in gel time. During hot summer months, no more than two months stability at 86 F/30 C should be anticipated.

DESCRIPTION
Firepel K133 series resins are specifical-
ly designed to be blended with alumina
trihydrate (ATH) to provide fire retardant
properties.

APPLICATION
Firepel K133-ATT-00 is thixotropic to keep
the ATH in suspension longer. ATH is
needed to provide fire retardant proper-
ties.

Flammability of composite parts is de-
pendent on the geometry of the part, de-
gree of cure, reinforcement content, types
of reinforcement, etc. It is the end user’s
responsibility to ensure that finished
parts meet the required specifications.
Published flammability properties should
be used for comparison purposes only.

BENEFITS
Fire Retardant
Laminates made with Firepel K133 se-
ries have passed the UL 94-HB, UL 94-
5V and UL 94-V-0 test requirements. Lami-
nates were made with a blend of 40/60
resin/ATH and 2 plies of 1.5 oz/450
grams/m2 chopped strand mat. (The
glass content was 22.5%)

Toxicity
Composites made with Firepel K133 series
resins have low toxicity values due to the
absence of halogens.

Low Cost
Economical Fire Retardant composites can
be made with Firepel K133 series resins.

Filler Guidelines for 150-160 phr ATH Resin Mixes
The particle size of the ATH filler will have a dramatic affect on the viscosity of the filled system. It has been
determined that a 50:50 blend of two different particle size grades of ATH will provide the optimum balance of
processing and reduce the tendency for the filler to settle. Alternate grades at similar mean particle size may
be considered. Some grades of ATH may affect the reactivity of the filled resin mixture, so it is advised to char-
acterize the specific grade of ATH before committing to production.

FIREPEL K133 SERIES POLYESTER 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 time and will help the fabricator make a high quality part. 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. After extended storage, some drift may occur in the product viscosity and gel time. SAFETY A. See appropriate Material Safety Da- ta Sheet for guidelines. B. Chemical resistance studies have indicated the dicyclopentadiene resins such as the Firepel K133 Series res- ins have inferior resistance to certain hydrophobic liquids, such as hydrocar- bons. Fuel storage tanks should not be produced with the Firepel K133 Series resins. If your manufacturing needs require a more corrosion resistant res- in, please contact your AOC representa- tive for information or technical assis- tance on AOC's line of isophthalic or vinyl ester resins. APPLICATION GUIDELINES A. Due to the curing characteristics of the Firepel K133 series resin, it is de- sirable 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 ensure 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 prod- uct. B. 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.

DESCRIPTION
Firepel K130 series resins are designed for
fire resistant applications where ASTM E
84 Class I flame is required. Flammability
of composite parts is dependent on the
geometry of the part, degree of cure,
reinforcement content, types of reinforce-
ment, etc. It is the end user’s responsibil-
ity to ensure that finished parts meet the
required specifications. Published flamma-
bility properties should be used for com-
parison purposes only.

Firepel K130-72 is the concentrated high-
ly brominated base resin that is used to
manufacture the other versions.

APPLICATION
Suitable for various fabricating methods
such as hand lay-up, spray-up, filament
winding, etc.

BENEFITS
Fire Retardant
Firepel K130 PT, NN and TT series meet
ASTM E 84 Class I flame spread require-
ments without the addition of fillers or
antimony.

Certain laminate constructions can meet
Class I smoke requirements. See
Flammability Property Table .

Low VOC
All Firepel K130 versions contain less than
35% styrene.

Versatile
The Firepel K130 series molecular archi-
tecture provides an excellent balance of
fire retardant, physical properties and cost.

1 – Laminates were 30-32 percent glass and post cured for 3 hours at 212 F/100 C.
2 – Smoke development of less than 450 is required for Class 1 rating.
** The degree of fire resistance of a cured resin is characterized by the ASTM E
84 test. This test is performed under strictly controlled conditions where a
flame spread rating is assigned according to comparisons with test set-point
materials. The behavior of the end-users composite cured under controlled
condition can vary significantly in an actual fire situation due to the large
number of unpredictable variables associated with actual fire situations.

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 time and will help the
fabricator make a high quality part.

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.

After extended storage, some drift may
occur in the product viscosity and gel
time.

SAFETY
See the appropriate Material Safety
Data Sheet for guidelines.
APPLICATION GUIDELINES
A. Halogen containing resins are gen-
erally less resistant to UV light than
general purpose resins. Fabricators
are advised to conduct their own tests
to determine the suitability of using
Firepel K130 Series resins for outdoor
applications.

B. Due to the curing characteristics
of the Firepel K130 Series resins, it is
desirable to complete all secondary
bonding as soon as possible. Exposure
of the laminate to sunlight will result in
severe secondary bonding, especial-
ly 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 prod-
uct. 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.

C. Chemical resistance studies have
indicated the dicyclopentadiene resins
such as Firepel K130 Series resins
have inferior resistance to certain hy-
drophobic liquids such as hydrocar-
bons. Fuel storage tanks should not
be produced with the Firepel K130
Series resins.

If your manufacturing needs require a
more corrosion resistant resin, please
contact your AOC representative for
information or technical assistance on
AOC’s line of isophthalic or vinyl ester
resins.

forth in this model to add value to the
resins we make for our customers.

FOOTNOTES
(1.) Based on tests of Firepel K130 base resin at
77 F/25 C and 50% relative humidity. All tests per-
formed on unreinforced cured resin castings. Thixo-
tropic components, if applicable are excluded from
casting samples. Castings prepared using 1.0% MEKP,
0.10% Cobalt 12%, post cured for 5 hours at 212
F/100 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.
