This product is a liquid two component polyurethane system that forms rigid foam with a nominal density of 3-4 lb. per cubic ft. that can be used for low-density insulation, structural or flotation applications. Higher densities can be made by restricting the expansion in closed molds. RV-series pigments can be added to the Component B before combining with the Component A. This product can be easily mixed by hand for small projects or machine dispensed for larger applications.

Clean Up

Dispose of all empty Molded Foam (3 lb. Density) component containers in accordance with local, state and federal regulations. Empty component containers can be rendered non-hazardous by rinsing the containers with a small amount of mixed material and allowing the solvents to evaporate. The containers will then contain non-hazardous cured urethane.

Storage and Shelf Life

Molded Foam (3 lb. Density) components are shipped from the factory in sealed containers that are purged with dry nitrogen. The containers should be kept tightly sealed and stored in a cool and dry area that is protected from direct sunlight and moisture. Storage temperatures should not exceed 80°F. The shelf life of factory sealed containers stored under these conditions is one year.
