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 thermodynamics 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.
