Two Part Liquid Urethane Expanding Foam 4-LB Density

Model:
1196|1205-Kit
$23.97

Our 4LB density foam is suited very well for flotation applications where you need a little more structural support. This foam is better sutied where you need to support tanks and under decks. If you are unsure what density to use, this foam will give a great combination of buoyancy and strength. This foam also works very well in taxidermy and other sculpting/carving applications.

  • This two-part liquid, expanding rigid urethane foam is a closed cell, pourable foam, which will resist the absorption of water.
  • The densities shown refer to the weight per cubic foot of expanded foam (12" x 12" x 12").
  • Once fully cured this foam can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting.
  • This product can be poured in multiple layers with excellent bonding between layers.
  • All expansion rates and times given are temperature critical. Temperatures below 75° F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75° to 80° F or above.
  • Accurate measuring of these products is extremely critical.
  • Working time before foaming: approx. 45 seconds
  • Time before full expansion: approx. 5 minutes
  • The lightweight foam is commonly used for filling voids, filling under decks and practically any other flotation or insulation application. Higher densities are used for architectural castings, support applications and has virtually an unlimited number of potential uses.
