It is the raw material of PU elastomer, coating and adhesives, which reacts with isocyanate to give a chemical grouting material that has been widely used for seepage-proofing and blocking up the loophole of tunnel, dam, underground projects and mine-pits, as well as foundation reinforcement. It also be used for defoaming in other areas.
