Liquid Urethane Foam, 8 pound Density, 4 lb Kit (1.7 qts)

Description

Overview:
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 degrees F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75 to 80 degrees F or above.
Accurate measuring of these products is extremely critical.
Find our selection of measuring containers and mixing equipment below.
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. Click on links below to go to these other items.
If used for casting always use a mold release and on pourus materials, seal mold and use Mold release.
