POLYESTER GEL COAT
POLYESTER GEL COAT FOR CLEAR SANITARY
WARE APPLICATIONS
Typical properties are not to be construed as specifications.
DESCRIPTION
Vibrin G440LU is a prepromoted, thixo-
tropic, neopentyl glycol isophthalic poly-
ester gelcoat designed for spray appli-
cations. It is designed for use in synthet-
ic marble applications.
BENEFITS
Low HAP content allows product to
meet composites MACT standards
Superior UV stability over conven-
tional products
Superior physical properties give
excellent thermal shock test results
Typical test results are more than
twice the ANSI Z124 thermal cycle
test requirement
Lower styrene emissions reduce
occupational exposures
Improved transfer efficiency with
less overspray generates less waste
No loss in processing characteristics
over conventional products.
Gives excellent color, clarity, air re-
lease and flow characteristics.
Pour times at 30-60 minutes are
typical

PERFORMANCE GUID ELINES
A. All AOC thixotropic polyester gel
coats should be mixed well prior to
use.
B. MEKP levels should be kept be-
tween 1.0% and 2.5%
C. Gel coats should not be applied
below 64 F/18 C.
D. Recommend spraying 3 passes
at 5-8mils allowing a short flash
time between passes
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 ac-
cepted 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 castings. Thixotropic components
are excluded from casting samples. Castings
were post cured.
(2) The gel times shown are typical but may be
affected by catalyst, promoter, inhibitor con-
centration, 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.

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 77 F/25 C.
Storage at elevated temperatures
will reduce shelf life.
After extended storage, some drift
may occur in gel time or viscosity.
SAFETY
See the appropriate Safety Data
Sheet for guidelines.
