Av-DEC’s pre-cured polyurethane linear gasket material has a polypropylene carrier for two-sided sealing. This material uses the same proven Av-DEC sealant technology to provide a moisture proof irregular surface barrier to prevent corrosion on both faying surfaces. The polyurethane demonstrates an exceptional balance between cohesion and adhesion which allows it to provide a consistent seal but remain easy to remove. The innovative polypropylene carrier provides a rigid mechanical stop to increase crush resistance.  This product is also available in die cut gasket form.  Common uses are under floor boards, lavatories, galleys, door sills and on top of stringers.  This product is also available in flame retardant (FR).
