Creating an Effective Seal with Dow Corning ® Sealant Strips
Gels combine two effects to create a seal. First, under compression gels can
conform around a variety of objects or irregular surfaces, so that the gel is
in contact with the entire surface of the object to be sealed. Once the
surfaces are in contact, the dynamics of the system favors the coating of the
surface by the gel versus by air or water. It is the combination of the gel's
ability to conform around a surface as well as to coat (or wet) the surface
that allows it to seal against air and water
