Title
(EN) ADDITION-TYPE SILICONE COMPOSITION FOR DENTAL USE
(FR) COMPOSITION DE SILICONE DE TYPE PAR AJOUT POUR USAGE DENTAIRE
(JA) 歯科用付加型シリコーン組成物
Abstract
(EN)
One embodiment of the present invention is an addition-type silicone composition for dental use, which contains a methyl phenyl polysiloxane and hydrophobic silica particles, and which does not substantially contain a surfactant. This addition-type silicone composition for dental use is configured such that: the hydrophobic silica particles have a BET specific surface area of 30 m2/g or more; and the mass ratio of the methyl phenyl polysiloxane to the hydrophobic silica particle is from 0.01 to 5.
(FR)
Selon un mode de réalisation, la présente invention concerne une composition de silicone de type par ajout, pour usage dentaire, qui contient un méthylphényle polysiloxane et des particules de silice hydrophobes et qui ne contient sensiblement pas de tensioactif. Cette composition de silicone de type par ajout pour usage dentaire est configurée de telle sorte que : les particules de silice hydrophobes ont une surface spécifique BET de 30 m2/g ou plus ; le rapport massique du méthylphényle polysiloxane sur les particules de silice hydrophobe est compris entre 0,01 et 5.
(JA)
本発明の一態様は、歯科用付加型シリコーン組成物において、メチルフェニルポリシロキサンと、疎水性シリカ粒子を含み、界面活性剤を実質的に含まず、前記疎水性シリカ粒子は、BET比表面積が30m/g以上であり、前記疎水性シリカ粒子に対する前記メチルフェニルポリシロキサンの質量比が0.01~5である。
