Ronabond® PU 55

Elastomeric Foaming Polyurethane Grout

Ronabond® PU 55 is an MDI based, single-component polyurethane resin. This system reacts rapidly when in contact with water to provide an elastomeric polyurethane closed cell foam seal capable of shutting down water leaks, seepage, and sealing cracks. Ronabond® PU 55 is a pre-catalysed low viscosity resin that is designed to form a resilient elastomeric seal in cracks and voids.
