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.
30A403D-S
Polyester Resin
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.

DESCRIPTION
Designed specifically for use on expanded polystyrene
foam. This
special polyester resin does not chemically attack EPS foam, but bonds,
and creates a barrier. Once cured, Styrosafe protects EPS foam from
chemical attack from general purpose unsaturated polyester resins or
styrene-containing coatings allowing low cost EPS foam to be
substituted for expensive urethane tooling board or MDF.

Use Instructions
Although StyroSafe Laminating Resin #30P-106A is compatible with low density polystyrene
foam, there are some precautions to follow when using the product:
Do not leave a puddle of resin on the foam after laminating onto the surface as some
chemical attack can occur due to excess exotherm development.
After the first, or skin coat, laminate has been applied, wait until it exotherms and
cools before following with the next laminates. Too much exothermic heat will melt the foam.
(1) Styrosafe needs to be catalyzed using an MEKP catalyst. We have used both Cadox L50 and
Norox 925 successfully in our testing and trials. Catalyze at 1.5% by weight.
(2) Apply at least two laminates made with StyroSafe resin before switching to a GP resin system
as the two laminates will insure that there will be no chemical attack of the foam.
NOTE: based on industry information about Expanded Polystyrene Foam we do not
recommend that the foam be subject to vacuum or temperatures above 160 F.
XPS FOAM OPTION: We are frequently asked whether StyroSafe can be used in conjunction
with XPS foam. StyroSafe was designed for best results with the cell structure of EPS foam – the
functionality and cell structure of XPS foam is functionally different. If you are working with
XPS foam, we advocate testing to your process to determine compatibility.

with XPS foam. StyroSafe was designed for best results with the cell structure of EPS foam – the
functionality and cell structure of XPS foam is functionally different. If you are working with
XPS foam, we advocate testing to your process to determine compatibility.

DERAKANE 510 B-400 epoxy vinyl ester resin is a low viscosity, unpromoted, flame retardant
(1)
epoxy vinyl ester. This resin offers exceptional processing characteristics including little to no
foaming, excellent exotherm control, and industry-leading storage stability. Laminates made with
DERAKANE 510 B-400 resin have achieved a flame spread of 25 (ASTM E-84). DERAKANE 510 B-400
resin gives final products with:
– Excellent flame retardancy
– High strength characteristics
– Excellent impact strength and toughness
– Fast wet-out and low drainage
– Excellent corrosion resistance to acidic and alkaline environments
Note: Contact us before using thixotropic agents and fillers. Addition of thixotropic agents and
fillers can compromise corrosion resistance.
APPLICATIONS AND
USE
DERAKANE 510 B-400 resin can be used for corrosion resistant, reinforced thermosetting plastic
equipment including filament wound, hand lay-up and spray-up tanks, pipes, ducts, stacks,
scrubbers, linings or other equipment handling corrosive gases, vapors or liquids where a high
degree of flame retardancy is required.
A pre-promoted version called DERAKANE 510 B-400 P resin is available. DERAKANE 411-350 resin
is a non-flame retardant epoxy vinyl ester which may be suitable for similar applications that do not
require fire retardance. DERAKANE 510 N resin can be used to fabricate laminates with improved
thermal resistance. Conditions for these resins are outlined in INEOS Composites’s Resin Selection
Guide at www.derakane.com. For recommendations on specific services and environments, please

(1) Laminates made with DERAKANE fire retardant resins will burn if provided with a sufficient
amount of heat and oxygen. The degree of flame retardancy of the cured resin is characterized by
the ASTM E-84 tunnel test. This test is performed under strictly controlled conditions where a flame
spread rating is assigned according to comparisons with test set-point materials. The behavior of
the cured composite under these controlled conditions can vary from an actual fire situation.
(2) Properties are typical values based on material tested in our laboratories. Typical values should
not be construed as a guaranteed analysis of any specific lot or as specification items.

For all surfaces that will be exposed to air during fabrication (top-coating, lining, patching, exterior
surfaces, etc.) the addition of 0.4% paraffin wax to the final resin layer is recommended. A waxed
surface may interfere with secondary bonding adhesion.
