Application

The product is the raw material of polyurethane elastomer, coating and adhesives, which react with isocyanate to give a chemical grouting material that has been widely used for seepage-proofing and blocking up the loophole of turnnel, dam, underground projects and mine-pits, as well as foundation reinforcement. They can also be used accompanied with rigid foam system.
