DESCRIPTION
Altek C431-PPC-18 is AOC s new gen-
eration acrylic bonding resin. It is a
pre-promoted, thixotropic polyester
resin.
APPLICATION
Altek C431-PPC-18 is designed to be
used with filler and has been carefully
engineered to maximize filler loading
without compromising quality of fin-
ished parts. It is used for backing vacu-
umed formed acrylic.
BENEFITS
Unique design for quicker hard-
ness development, which speeds
up mold turnover and increases
rate of production
Excellent adhesive to formed acryl-
ic resulting in greater integrity of
the laminate and finished parts
Capable of higher filler loading
without loss of physical properties
insuring that as filler is increased,
the rate of cracking at demold
does not increase which maximiz-
es the end product
Designed for improved wet out and
roll out of the laminate

ALTEK
C431-PPC-18 POLYESTER RESIN
PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% (1.25% mini-
mum with mechanical application)
of the total resin weight.
B. Maintaining shop temperatures be-
tween 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 condi-
tions contribute to consistent gel times
viscosity.
STORAGE STABILITY
Resins are stable for three months
from the date of manufacture 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 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), in particular trans-
lucent PE/PP, will accelerate gel for-
mation and result in a significantly
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.
APPLICATION GUIDELINES
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.
ISO 9001:2015 CERTIFIED
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
resins we make for our customers.
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.

CORVE8730 is a non-promoted, epoxy novolac-based vinyl ester resin. This high cross-link density resin has a heat
distortion point of 280 F (138 C) and exceptional chemical resistance. Typical uses are filament winding and hand lay-up
of reinforced plastic tanks, pipe and process equipment, etc. Its high heat distortion point also makes this resin an
outstanding choice for high temperature applications.
FEATURES BENEFITS
High Physical Properties Makes extremely tough composites
Highly Versatile Viscosity Properties Formulated for spray-up and hand lay-up needs
Non-Promoted Resin System Able to adapt to customer-specific conditions
Outstanding Corrosion Resistance Resists caustic and solvent with hydrolytic stability
High Heat Distortion Resistance Maintains dimensional stability
