Polyurea Grouting Sealant Application in the Field of Concrete Expansion Joints

Polyurea grouting sealant is an efficient waterproof and leak-stopping material and plays an important role in the field of construction engineering. It is generated by the reaction of an isocyanate component with an amino compound. The isocyanate component can be a monomer, polymer, derivative of isocyanate, prepolymer or semi-prepolymer.
