Abstract
L'invention concerne des compositions binaires améliorées à base de polyorganosiloxane polymérisable, convenant en particulier pour la prise d'empreintes dentaires, qui présentent une résistance accrue à la déchirure, et une mouillabilité également accrue. La résistante accrue à la déchirure résulte de l'inclusion d'un polysiloxane quadri-fonctionnel possédant une teneur en vinyle comprise entre 0,16 et 0,24 m-moles/g. Le temps d'emploi est prolongé grâce à l'inclusion de quantités suffisantes d'un retardateur de prise qui retarde le départ de la polymérisation du vinyle. On a accru la mouillabilité en incluant un tensioactif produisant un angle de contact superficiel avec l'eau de moins de 50· à trois minutes. Le tensioactif choisi présente un rapport hydrophile-lipophile (HLB) de 8-11, ce qui fait que l'angle de contact mouillant est atteint en moins de deux minutes, et qu'il reste mouillant pendant tout le temps d'emploi nécessaire à la prise d'empreinte, améliorant ainsi sensiblement la qualité de prise d'empreinte. On obtient un matériau de prise d'empreinte à basse viscosité comprenant un composant basique et un composant catalyseur. Les deux composants sont des matériaux à base de siloxane.
