Organically Modified Silicates (Ormosils) as Adhesives for Siliceous Surfaces

Abstract Adhesion to glass surfaces still may be a problem under “heavy duty” conditions such as temperature and moisture or both. In many cases the problem may be overcome by use of adhesion promoters such as reactive silanes. These silanes remove water films from the glass surface by chemical reaction, are able to form chemical bonds to the glass surface and, in addition to this, can have an affinity to the sealing material to be used. A decay of adhesion strength between glass and a seal under wet conditions is caused by the following effect:
