The polyurethane foam is obtained by combining two unique components in equal quantities with a pump/ reactor connected to a spray gun. The expansion of the foam is 100% water-based without any blowing agent (the water contained in the resin contributes to the foam expansion when it is mixed with MDI in the gun chamber).


Icynene LD-C-50R is an open cell spray foam insulation which is not hazardous to health for walls, roofs, closed cavities, new and existing drylining and floors.
