Compositions that are curable by free radical redox reactions are disclosed. Free radical curing reactions between polythiols and polyalkyenyls are initiated by the reaction of metal complexes and organic peroxides. The compositions are useful as sealants.

Dual cure sealants

Photocurable adhesion-promoting compositions containing organic titanates and/or organic zirconates and partially reacted alkoxysilanes and the use of the photocurable adhesion-promoting compositions to provide adhesion between metal substrates and an overlying radiation-cured sealant are disclosed.

Photocurable adhesion-promoting compositions and methods of use

Adhesion-promoting compositions containing organic titanates and/or organic zirconates and the use of the adhesion-promoting compositions to provide adhesion-promoting layers to enhance adhesion between metal substrates and an overlying free radical-polymerized sealant are disclosed.

Adhesion-promoting interlayer compositions containing organic titanates/zirconates and methods of use

Adhesion-promoting compositions and the use of the adhesion-promoting compositions to provide adhesion-promoting interlayers to enhance adhesion between adjoining layers of sulfur-containing sealants are disclosed. In repair applications, the adhesion-promoting compositions can enhance the adhesion of an overlying radiation-curable sulfur-containing sealant to a damaged or aged sulfur-containing sealant.
