Styrosafe is extremely flammable. Do not apply near sparks, open flames or heat.
Keep area v entilated. Do not smoke. Avoid continuous breathing of vapor.
Styrosafe contains ingredients which could be harmful if mishandled. Contact with
skin and eyes should be
avoided and necessary protective equipment and clothing
s
hould be worn. Individuals should was h with soap and water before eating or
drinking. All containers s
hould be properly labeled to prevent accidental ingestion
or improper disposal. I
ndividuals s hould reseal any partly used material back in the
container. Store under c
ool, dry conditions and away from open flames and high
temperatures.

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.
