Foamed-in-place gaskets are created by mixing inert nitrogen gas into the uncured sealant during the application. As the material is dispensed the gas expands resulting in a homogeneous mixture that forms a closed-cell foam. The material is then cured-in-place before final assembly of the flange joint. NOVAGARD® Silicones UV cured sealants maintain all of the enhanced performance characteristics of conventional silicone based materials with processing speeds unmatched by other technologies. This technique requires special dispensing and foaming equipment such as the SureFoamTM Dispensing System available from Nordson Corporation.
