AV-248-LV Flexseal LV is a low viscosity, moisture activated, MDI-based polyurethane resin whose reaction is catalyzed by mixing AV-249-LV Flexseal Cat LV with AV-248-LV. Injected as a single component, AV-248-LV is designed to seal active and potential water leaks in various cracks and annular space where flexibility is needed but is susceptible to wet/dry cycles. AV-248-LV cures resilient, impermeable, and flexible.
AV-249-LV Flexseal Cat LV is the catalyst designed exclusively for AV-248-LV Flexseal LV. Typically, one container of AV-249-LV is used per 5-gallon container of AV-248-LV. Depending on the desired reaction time, AV-249-LV may be doubled.
AV-248-LV Flexseal LV is tested and certified for NSF/ANSI/CAN 61 - Drinking Water System Components.
