Description
Revchem 30A403D-S is a
medium reactive, thixotropic,
pre-promoted resin designed
for use in the manufacturing of
boats and other composite parts
using hand lay-up or spray-up
application methods.
Features & Benefits
Fast laminate cure allows for
faster production rates without the
loss of surface profile.
Reduced post cure.
Fast and complete fiber wet-out.
Good resistance to osomotic
blistering. (For improved blister
resistance, a skin coat made with
Hydropel
H034-A, H100-W or
H100-M can be used)
Will provided good physical
properties in finished part.
Adaptable to a variety of
manufacturing processes and
conditions.
Meets MACT requirements for low
HAP resins in the marine industry.

PERFORMANCE GUIDELINES
A. Keep full strength catalyst levels
between 1.0% – 2.0% if 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 conditions
contribute to consistent gel times.
C. Sanding and/ or grinding is
recommended 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 date of manufacture when stored
in the original containers away from
direct sunlight or other UV light sources
and at or below more than 77 F/25 C.
Storage stability of two months or less
should be anticipated if the storage
temperature exceeds 86 F/30 C.
After extended storage, some drift may
occur in the product viscosity and gel
time.
SAFETY
See appropriate Material Safety Data
Sheet for guidelines.
APPLICATION GUIDELINES
Due to the excellent curing
characteristics of Revchem 30A403D-S
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 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.
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.
Chemical resistance studies indicate
that resins like 30A403D-S have very
poor resistance to certain hydrophobic
liquids, such as hydrocarbons. Fuel
storage tanks should not be produced
with the Revchem 30A402D-S resin.
If your manufacturing needs require a
more corrosion resistant resin, please
contact your Revchem Composites
representative for information or
technical assistance on Revchem s
line of isophthalic or vinyl ester resins.
FOOT NOTES
(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
inhibitor concentrations and resin, mold
and shop temperature. Variations in
gelling characteristics 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 fabricator check
gelling characteristics of a small quantity
of resin under actual operating conditions
prior to use.
