Data Sheet StyroSafe Laminating Resin

A pre-accelerated, orthophtalic, unsaturated polyester resin, diluted in styrene and methacrylic monomer with medium reactivity and medium viscosity.

Usage
For laminating directly on polystyrene low-density foam without an
intermediate barrier. StyroSafe is formulated for applications where
adhesion to an expanded polystyrene is required. These applications
could include surf and windboards; CNC-shaping of patterns and
models; lamination of hot-wire cut foam; decorative foam for building
facades; floating docks; and thermal insulation barriers..

Safety: The product is flammable and harmful. Further information is provided in the safety data sheet.

Application Information
Although StyroSafe Laminating Resin #30P-121 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 "skincoat," laminate has been applied, wait until it
exotherms and cools before following with the next laminates. Too
much exothermic heat will melt the foam.
• Catalyze at the full 2% with mekP catalyst and never use a 30% or
lower reactivity catalyst.
• 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.
