Abstract
This invention relates to enchancing the bonding of polysulfide sealants to a variety of inorganic substrates, most particularly, to metal, ceramic, concrete, and glass substrates. This improved bonding of sealant is achieved by the use of a silane adhesion promoter which is characterized by the following formula: EQU R -- SiX.sub.3 wherein R is a norbornenyl, bicyclopentenyl, or a mercaptonorbornyl containing radical, and "X" is a hydrolyzable group.
