| description | To provide glass Ionomer compositions that have improved storage stability while retaining the mechanical strength (e.g., flexural strength and fracture toughness).SOLUTION: A first paste includes water, a polyacid, and a non acid-reactive filler. A second paste includes water, an acid-reactive filler, and non-aggregated, water-miscible, nano-sized silica particles having at least 25% surface coverage of the particles with a silane. The composition is essentially free of a resin. In some embodiments, the water content of the first paste and the second paste of the paste/paste GI composition disclosed herein is less than 20 wt.%, based on the total weight of the composition.SELECTED DRAWING: None
【課題】機械的強度（例えば、曲げ強度及び破壊靭性）を維持しながら、貯蔵安定性が向上したグラスアイオノマー組成物を提供する。【解決手段】第１ペーストは、水、ポリ酸、及び非酸反応性充填剤を含む。第２ペーストは、水、酸反応性充填剤、及びシランによる粒子の表面被覆率が少なくとも２５％である非凝集性かつ水混和性のナノサイズシリカ粒子を含む。組成物は樹脂を本質的に含まない。いくつかの実施形態では、本明細書に開示されるペースト／ペーストＧＩ組成物の第１ペースト及び第２ペーストの含水率は、組成物の全重量を基準として２０重量％未満である。【選択図】なし |
