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.

Advantages

• Safer than TDI based products
• Low viscosity
• Resistant to mild acids, alkalis and common chemicals
• Non-flammable
• Single component
• Form a flexible elastomeric closed cell foam seal
• Maintains seal under repeated wetting cycles
• Accommodates movement and vibration

Usage

• High speed sealing of leaking cracks
• Back grouting and sealing
• Sealing pipe joints and tunnel sections
