To compare the evaporation of vehicles included in different single-bottle adhesives as a function of time.
The following adhesives were used: Prime and Bond 2.1 (Dentsply); Single Bond (3M); PrimaBond 97' (BJM); Syntac Sprint (Vivadent); Optibond Solo (Kerr) and Syntac Single Component (Vivadent). Two primers that are used in multiple-component adhesives (PermaQuick Primer, Ultradent and Scotchbond Multipurpose Primer, 3M) as well as distilled water, 96% ethanol and acetone were also included in the experiment. Samples of these products were stored in small glass containers under controlled temperature and humidity conditions. Initials mass and mass after different periods of time were registered to calculate the percentage loss of mass.
The analysis of variance of the results followed by orthogonal contrast comparisons revealed a significantly higher loss of mass in the single-bottle adhesives that contain organic vehicles (especially in those in which the vehicle was acetone). A somewhat lower loss of mass was found in a water-based product.
There is a relationship among the evaporation possibilities of the vehicles used in single-bottle adhesive systems and their loss of mass during storage.
比较不同单瓶装粘合剂中载体随时间变化的蒸发情况。
使用了以下粘合剂：Prime and Bond 2.1（登士柏公司）；Single Bond（3M公司）；PrimaBond 97'（BJM公司）；Syntac Sprint（唯沃文特公司）；Optibond Solo（克尔公司）以及Syntac单组分粘合剂（唯沃文特公司）。实验中还纳入了用于多组分粘合剂的两种底漆（PermaQuick底漆，登士柏公司；以及Scotchbond多功能底漆，3M公司），以及蒸馏水、96%乙醇和丙酮。将这些产品的样品储存在小玻璃容器中，置于可控的温度和湿度条件下。记录初始质量和不同时间段后的质量，以计算质量损失百分比。
对结果进行方差分析并随后进行正交对比比较显示，含有有机载体的单瓶装粘合剂（尤其是载体为丙酮的那些）质量损失显著更高。在一种水性产品中发现质量损失略低。
单瓶装粘合剂系统中使用的载体的蒸发可能性与其储存期间的质量损失之间存在关联。
