Product Overview
Oil-soluble polyurethane foam water stop is a high-molecular chemical grouting material synthesized through polymerization reactions between polymeric MDI (diphenylmethane diisocyanate) and polyhydroxy polyethers. It delivers immediate leakage-stopping effects for emergency water containment, structural reinforcement of concrete, and ground stabilization.
Performance Characteristics
-
Excellent water miscibility: Rapidly polymerizes, foams, and expands upon injection, bonding with sand/soil to form a rigid solid that instantly seals cracks for permanent waterproofing.
-
Adjustable curing time: Post-reaction foaming time can be controlled from seconds to several minutes.
-
High expansion, zero shrinkage: Strong adhesion to substrates after curing, with high post-foaming strength.
-
Good storage stability: Cures reliably even at low temperatures. Low exothermic heat, simple application, and easy cleanup.
-
Customizable production: Safe, oil-soluble polyurethane grout tailored to client needs for inspection, maintenance, and emergency repair.
