Title (EN) PHOTOCURABLE COMPOSITIONS AND METHODS FOR 3D PRINTING USING THEM
(FR) COMPOSITIONS PHOTODURCISSABLES ET PROCÉDÉS D’IMPRESSION 3D LES UTILISANT
Abstract:
(EN) The present disclosure relates generally to photocurable compositions and methods for continuously forming a three-dimensional body from these compositions. More particularly, the present disclosure relates to photocurable compositions comprising a mixture of polysiloxanes capable of being dually cured, i.e., first by UV radiation followed by thermal treatment, or being cured by UV radiation. In one aspect, the disclosure provides a photocurable composition, including: a first polysiloxane comprising at least two acrylate or methacrylate groups per molecule; a second polysiloxane containing at least one (e.g., at least two) Si-H group per molecule; a third polysiloxane containing at least one (e.g., at least two) reactive aliphatic ethylene group per molecule; a free radical photoinitiator in an amount of about 0.01 to about 10 weight % based on the total weight of (meth)acrylate-containing polysiloxane in the composition; and a hydrosilylation catalyst in an amount of about 0.001 to about 10 weight % hydride-containing polysiloxane and vinyl-containing polysiloxane in the composition.
(FR) La présente invention concerne de manière générale des compositions photodurcissables et des procédés de formation continue d'un corps tridimensionnel à partir de ces compositions. Plus particulièrement, la présente invention concerne des compositions photodurcissables comprenant un mélange de polysiloxanes pouvant être doublement durci, c'est-à-dire, tout d'abord par rayonnement UV suivi d'un traitement thermique, ou étant durci par un rayonnement UV. Dans un aspect, l'invention concerne une composition photodurcissable, comprenant : un premier polysiloxane comprenant au moins deux groupes acrylate ou méthacrylate par molécule ; un deuxième polysiloxane contenant au moins un groupe (par exemple, au moins deux) groupe Si-H par molécule ; un troisième polysiloxane contenant au moins un (par exemple, au moins deux) groupe éthylène aliphatique réactif par molécule ; un photoinitiateur radicalaire en une quantité d'environ 0,01 à environ 10 % en poids sur la base du poids total de polysiloxane contenant un (méth)acrylate dans la composition ; et un catalyseur d'hydrosilylation en une quantité d'environ 0 001 à environ 10 % en poids de polysiloxane contenant de l'hydrure et du polysiloxane contenant du vinyle dans la composition.
