DESCRIPTION
The Firepel K140 Series are halo-
gen-free fire retardant resins spe-
cifically designed for mass trans-
portation and architectural appli-
cations. This unique fire retardant
resin requires no additional fillers
or additives to achieve composite
parts with superior flame spread
and smoke development/toxicity
properties.
APPLICATIONS
Mass Transportation
Architectural
Building/Construction
BENEFITS
Meets globally recognized
mass transportation standards
Meets low smoke toxicity re-
quirements in US, Europe and
Asia
Meets ASTM E 84 Class 1
flame and smoke require-
ments
Provides reduced weight com-
pared to ATH filled composites
Formulated for improved stor-
age stability
Pre-accelerated and requires
only Cobalt and MEKP

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.
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 certifi-
cation recognizes that each AOC
facility has an internationally accept-
ed model in place for managing and
assuring quality. We follow the prac-
tices set forth in this model to add
value to the resins we make for our
customers.
FOOTNOTES
(1) The gel times shown are typical but may be
affected by catalyst, promoter, inhibitor concen-
tration, resin, mold, and shop temperature.
Variations in gelling characteristics can be ex-
pected between different lots of catalysts and at
extremely 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.
(2) *Flammability, toxicity and smoke development
of composite parts is dependent on many variables,
including the geometry of the part, the degree of
cure of the laminate, reinforcement types - among
many others. It is the end user s responsibility to
ensure that finished parts meet the required specifi-
cations. Published flammability properties should be
used for comparison purposes only.
(3) All testing was performed on a 3 ply 1.5 ounce
CSM laminate at 22% glass. Post curing for 4 hours
at 180 F/82 C prior to testing at third party accredit-
ed testing facility. Resin was prepared using 1.5%
MEKP and 0.25% Cobalt 12%.
