DUAL CURE SEALANTS

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. L'invention concerne des compositions...

Zusammenfassung:	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. L'invention concerne des compositions durcissables par des réactions d'oxydo-réduction radicalaire. Des réactions de durcissement radicalaire entre des polythiols et des polyalkyényles sont initiées par la réaction de complexes métalliques et de peroxydes organiques. Les compositions sont utiles en tant que produits d'étanchéité.
