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.

FIREPEL
K130 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
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.
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 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.

Despite the general flame retardancy of
this series of products, any laminate or
other products made with fire retardant
resins will burn if subject to an environ-
ment with a sufficient amount of heat
and oxygen.
