AV-258-LV PermaFlex LV

AV-258-LV PermaFlex LV™ is a moisture activated MDI-based polyurethane resin. The water/moisture activation is a two-step chemical reaction and is catalyzed by mixing AV-259-LV PermaFlex Cat LV ™ with AV-258-LV. Injected as a single component, AV-258-LV is designed to react quickly with moisture to seal active and potential water leaks in cracks or small annular spaces that are susceptible to wet/dry cycles and where flexibility is needed. AV-258-LV should always be injected into small, narrow, confined spaces to provide restricted expansion of the grout. AV-258-LV cures flexible and impermeable.

AV-259-LV PermaFlex Cat LV is the catalyst designed exclusively for AV-258-LV PermaFlex LV. Typically, one container of AV-259-LV Cat is used per pail of AV-258-LV. Depending on the desired reaction time, AV-259-LV Cat may be doubled.

AV-258-LV PermaFlex LV is tested and certified for NSF/ANSI/CAN 61 - Drinking Water System Components.
