ABSTRACT:
Method and composition for selectively removing liquid hydrocarbon from floors and other hard surfaces comprising granular polyisocyanurate foam. The composition desirably includes a particulate material having a bulk density greater than the polyisocyanurate foam for increasing the overall bulk density of the composition and imparting slip resistance to the floor or hard surface. Suitable particulate material includes angular sand and comminuted cellular glass. The granular polyisocyanurate foam and particulate material can be supplied from scrap material to reduce cost and landfill waste.
