Semfoam™ sealant is an engineered sealant solution for aircraft design issues. Semfoam™ sealant is an open-cell, inert polyurethane foam which has been precisely cut to a pre-agreed shape, then accurately loaded with the appropriate aerospace sealant and snap frozen. Semfoam™ sealant is normally supplied as a kit made up of several pieces that will, when assembled together, fill a particular cavity on the aircraft.

Some of the benefits offered by Semfoam™ sealant are:

Increases the speed of the sealing operation by eliminating the need to build up sealant in layers for large apertures

There is no sealant waste and the packaging can be returned to PPG Aerospace, cleaned and re-used repeatedly

Semfoam™ sealant assumes the precise shape of the of the aperture to ensure that all potential gaps are filled, eliminating air pockets
