Tray adhesive, which is used for the adhesion of elastomer rubber impression materials to a custom resin tray, lowers the retention of the impression materials to the impression modeling plastics, as some ingredients of tray adhesive make the impression modeling plastic soft and tacky.
The efficacy of tray adhesive, which is used for the adhesion of elastomer rubber impression materials to a custom resin tray, on the adhesion between elastomer rubber impression material and impression modeling plastic was investigated.
Four silicone rubber impression materials (two addition reaction types and two condensation reaction types), two polysulfide rubber impression materials, and one impression modeling plastic were used in this study. Tensile strength between elastomer rubber impression material and impression modeling plastic with or without the application of tray adhesive was evaluated.
Although tray adhesives for both addition reaction type and both condensation reaction type of silicone impression materials and one tray adhesive for polysulfide rubber impression material increased the tensile strength between the impression material and impression modeling plastic, one tray adhesive for polysulfide rubber impression material decreased the tensile strength when sufficient drying time was not applied.
托盘粘合剂用于将弹性体橡胶印模材料粘附到定制树脂托盘上，但由于托盘粘合剂的某些成分会使印模成型塑料变软且发粘，从而降低了印模材料与印模成型塑料之间的附着力。
研究用于将弹性体橡胶印模材料粘附到定制树脂托盘上的托盘粘合剂对弹性体橡胶印模材料与印模成型塑料之间附着力的影响。
本研究使用了四种硅橡胶印模材料（两种加成型和两种缩合型）、两种聚硫橡胶印模材料和一种印模成型塑料。评估了使用或不使用托盘粘合剂时弹性体橡胶印模材料与印模成型塑料之间的拉伸强度。
尽管用于加成型和缩合型硅橡胶印模材料的托盘粘合剂以及一种用于聚硫橡胶印模材料的托盘粘合剂提高了印模材料与印模成型塑料之间的拉伸强度，但当未给予足够的干燥时间时，一种用于聚硫橡胶印模材料的托盘粘合剂会降低拉伸强度。
