AV-248-LV Flexseal LV
AV-248-LV Flexseal LV is the low viscosity version of the original AV-248. Injected as a single component, catalyzed AV-248-LV Flexseal LV is a moisture activated MDI-based polyurethane resin. The chemical reaction is catalyzed using AV-249-LV Cat-LV and uses moisture as an initiator. Like other hydrophobics, AV-248-LV Flexseal LV withstands wet/dry cycles and reacts with moisture; but unlike all other hydrophobics, it forms a resilient, impermeable flexible foam. Designed for sealing active and potential water leaks in various cracks and annular spaces where flexibility is needed but is susceptible to wet/dry cycles.
AV-248-LV Flexseal LV is tested and certified by the Water Quality Association (WQA) against NSF/ANSI 61 - Drinking Water System Components.
