ISO 9001:2008 CERTIFIED
The Quality Management Systems
at every AOC manufacturing facil-
ity have been certi ed as meeting ISO
9001:2008 standards. This certi cation
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 and inhibi-
tor concentrations and resin, mold and shop
temperature. Variations in gelling character-
istics can be expected between different lots
of catalysts and at extremely high humidities.
Pigment and fillers can retard or accelerate
gelation. It is recommended that the fabri-
cator 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% 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 condi-
tions contribute to consistent gel times.
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 tem-
perature exceeds 86 F/30 C.
After extended storage, some drift may
occur in the product viscosity and gel time.
Storage in plastic totes made out of materi-
als such as polyethylene (PE) or polypro-
pylene (PP) in particular translucent PE/
PP, will accelerate gel formation and result
in a signi cantly reduced storage stability.
Storage of this resin outdoors in translu-
cent plastic totes may reduce the storage
stability to only a few weeks. AOC cannot
assume responsibility for gel formation
under these storage conditions.

C949-F Series
Polyester Resin
APPLICATION GUIDELINES
Due to the excellent curing character-
istics of the Altek C949-F series resin,
complete all secondary bonding as soon
as possible. Exposing the laminate to
sunlight will result in severe secondary
bonding problems. After 24 hours of
cure, it may be necessary to abrade the la-
miante to insure good secondary bonding,
especially if the surface of the laminate is
resn rich. Avoid low berglass content
and resin puddling with this product.

Sheet for guidelines.
