AV-330-NTP Safeguard NTP is a 100% MDI-based, single component, mid-range viscosity, moisture activated polyurethane injection resin designed for sealing active leaks in below-grade structures. AV-330-NTP permeates well in various cracks and joints, but offers added safety in confined spaces or where there is poor ventilation. AV-330-NTP cures to a resilient and flexible, yet tough, closed-cell foam.
AV-330-NTP is equivalent to AV-330 Safeguard, however NOT certified for use in potable water.
