| single Component Rigid Polyurethane Foam |
DHP-2000 Rigid Polyurethane Foam is a single component hydrophobic water cut-off grout and soil stabilization grout based on a MDI (methylene-dephenylisocyanate) polyurethane. grouting chemical for concrete Upon contact with water DHP-2000 reacts to a foam while expanding its volume up to 30 times. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.
