Hydrophilic And Hydrophobic Polyurethane Grouting
Water-soluble means that the material is a hydrophilic material:
when the water and water-soluble polyurethane foam expansion, met the water again will continue to absorb moisture expansion; the same time water-soluble polyurethane in water swelling elastic colloidal solid , The state is similar to a sponge, soft.
Oil-soluble means that the material hydrophobic material:
when the water and oil-soluble polyurethane foam expansion curing, the water encountered again will not absorb moisture; at the same time oil-soluble polyurethane grouting in the water after the expansion of rigid foam-like solidified body.
