The present invention provides novel dental impression materials, the cure of which can be monitored visually, comprising: (1) a curable silicone polymer; (2) a crosslinker compound containing silicon-bonded-hydrogen groups; (3) a hydrosilation catalyst; and (4) one or more cure-indicating dyes that exhibit a color change in the presence of a silicon-bonded-hydrogen compound and a hydrosilation catalyst. The cure-indicating dye provides the composition with an initial pre-cure color and a different post-cure color. As a result of this change in color, the state of cure of the impression material can be visually monitored.
本发明提供了一种新型的牙科印模材料,其固化过程可以通过视觉监测,包括:(1)可固化的硅氧烷聚合物;(2)含有硅键合氢基团的交联剂化合物;(3)氢硅化催化剂;以及(4)一种或多种固化指示染料,其在存在硅键合氢化合物和氢硅化反应催化剂的情况下显示颜色变化。固化指示染料为该组成物提供了初始的预固化颜色和不同的固化后颜色。由于颜色的变化,印模材料的固化状态可以通过视觉监测。
