Patent

CA 2316198

The invention relates to the use of an adhesive containing components A, B and C, where component A contains a compound with at least one epoxy group, component B contains a compound with at least 3 OH groups and component C contains a photo-initiator which after irradiation with light at a wave length of between 100 and 600 nm initiates a polymerisation of components A and B, for the production of films and materials. Use of the adhesive according to the invention yields composite films presenting high heat-resistance, low migration and high flexibility.

L'invention concerne l'utilisation d'un adhésif renfermant les constituants A, B et C, le constituant A contenant un composé avec au moins un groupe époxy, le constituant B contenant un composé avec au moins 3 groupes OH et le constituant C contenant un photo-initiateur qui, après exposition à de la lumière d'une longueur d'onde de 100 à 600 nm, amorce une polymérisation des constituants A et B, pour la production de films et de matériaux. L'utilisation de l'adhésif selon l'invention donne des films composites présentant une résistance thermique élevée, une faible migration et une grande souplesse.
