The invention concerns a composition cross-linkable under radiation. This composition has a base of at least one polyorganosiloxane with cross-linkable functional groups, and is characterised in that said composition contains a stabilising amine agent, and an initiator system for hardening under radiation, in particular UV radiation, said composition being stable for use and storage. The amine agent is a secondary or tertiary amine of formula (VIII), a sterically congested cyclic amine of formula (IX), or an amine consisting of patterns of formulae (VIII) and (IX) mutually linked.
La présente invention a pour objet une composition réticulable sous radiation. Cette composition est à base d'au moins un polyorganosiloxane à groupements fonctionnels réticulables, et est caractérisée en ce que ladite composition comprend un agent aminé stabilisant, et un système amorceur de durcissement sous radiation, en particulier U.V., ladite composition étant stable à l'emploi et au stockage. L'agent aminé est une amine secondaire ou tertiaire de formule (VIII), une amine cyclique encombrée stériquement de formule (IX), ou une amine constituée de motifs de formules (VIII) et (IX) reliés entre eux.
