据报道，底漆可以增加用于颌面假体的有机硅弹性体和聚氨酯衬垫之间的附着力。本研究评估了两种引物、三种聚合方法和七种引物反应时间，以确定最佳粘合强度的条件。试样的t型剥离强度按照ASTM标准D 1876-72的描述进行测定。对失效模式进行评估，采用双样本t检验和单因素方差分析比较显著（P < 0.05）差异的均值。无论聚合方法或底漆反应时间如何，用处理剂1205处理的聚氨酯的粘结强度明显大于S-2260。任何单一的聚合方法或单一的引物反应时间都不能产生更大的结合强度。
Primers have been reported to increase adhesion between silicone elastomers and polyurethane liners used for maxillofacial prostheses. This study evaluated two primers, three polymerization methods, and seven primer reaction times to determine the conditions for optimum adhesive bond strength. The T-peel strength of specimens was determined as described in ASTM Standard D 1876-72. Failure modes were evaluated, and two-sample t tests and one-way ANOVA were used to compare means for significant (P < .05) differences. Bond strengths were significantly greater for polyurethane treated with primer 1205 rather than S-2260 regardless of the polymerization method or primer reaction time. Neither any single polymerization method nor single primer reaction time consistently yielded greater bond strengths.
