AV-333 Injectaflex is a single component, mid-range viscosity, moisture activated polyurethane resin designed for sealing active water leaks in cracks or joints in below-grade structures. AV-333 has the added benefit of containing dimethyl ketone (acetone) – a highly hygroscopic chemical able to attract surrounding atmospheric moisture and dissolve FOGs (fats, oils, and greases) to ensure good adhesion on various surfaces. It cures to form a resilient and flexible, yet tough, closed-cell foam.
AV-333 Injectaflex is certified for NSF/ANSI 61 - Drinking Water System Components.
Since the discontinuation of 3M Scotch-Seal 5600 in 2006, Avanti offers AV-333 with equal specifications.
