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.
Claims15
Method for removing liquid hydrocarbon from floors and other hard surfaces comprising the steps of:
- applying to the liquid hydrocarbon on the floor or other hard surface a composition comprising a mixture of:
- absorbent granular polyisocyanurate foam having a first bulk density for absorbing the liquid hydrocarbon;
- and
- a particulate abrasive material having a second bulk density greater than the first bulk density for imparting slip-resistance to the floor or hard surface;
- and
- after the composition has absorbed at least a portion of the liquid hydrocarbon, removing the composition from the floor or other hard surface.
