优选地，经过组装的物品的形成在低于35℃，更优选地20℃到30℃的温度下进行。为了促进粘着剂组合物中异氰酸酯基与羟基之间的固化反应，优选地将经过组装的物品加热到高于35℃的温度，更优选地加热到40℃到60℃的温度。任选地，可以将经过组装的物品在35℃或更高的温度下保持8周或更少；更优选地6周或更少的时段。如果在涂覆粘着剂组合物之后使经过组装的物品暴露于机械压力下，那么可以任选地在施加压力时将经过组装的物品保持在高于35℃的温度下，并且所述温度任选地在经过组装的物品上的不同位置处不同。任选地，可以在高于35℃的一个温度下涂覆粘着剂组合物，并且经过组装的物品中暴露于机械压力下的部分可以处于高于35℃并且与涂覆粘着剂组合物时的温度不同的温度下。
优选的是粘着剂组合物在25℃下是液体。更优选的是粘着剂组合物在25℃下粘度相对较低，以便有助于将粘着剂组合物的层涂覆于衬底表面上的工艺。
当使经过组装的物品暴露于高温中以促进固化反应时，需要粘着剂组合物的粘度在一段时间(“凝固时间(open time)”)内保持较低，以便允许在必要时进行再定位。然而，需要凝固时间相对较短。进一步需要，在凝固时间之后，粘着剂组合物的粘度快速增加。认为尽管粘着剂组合物可能尚未充分固化，但粘度的快速增加将在衬底之间形成粘结(称作“生粘性”)，其将允许在衬底不相对于彼此滑移的情况下轻轻地操纵和/或移动经过组装的物品。还需要在使粘着剂组合物充分固化时，衬底之间的粘结应相对较强，甚至在暴露于高温中和/或暴露于水、油、食品或其它化学品中之后仍较强。
以下是本发明的实例。
在以下实例中，使用以下术语：
F＝官能度。对于多元醇，这意味着每分子的羟基数目。对于多异氰酸酯，这意味着每分子的异氰酸酯基数目。对于混合物或分布，F是数目平均官能度。
OHN＝羟值
Visc50＝50℃下的粘度，通过锥形和平板流变仪在10sec-1下测量。流变仪是来自安东帕公司(Anton Paar)的MCR 301型。
HDI＝十六基-1,6-二异氰酸酯
EG＝乙二醇
DEG＝二乙二醇
TMP＝三羟甲基丙烷
Mw＝重量平均分子量
在以下实例中，使用以下多元醇。仅多元醇B1是上文所描述的聚合多元醇(B)的实例。
使用以下多异氰酸酯：
NCO1＝HDI三聚体
NCO2＝TDI和聚乙二醇预聚物
制造以下粘着剂组合物。比较性粘着剂标记有“-C”后缀。所示的量是重量份。
粘着剂组合物(重量份)
| 编号 | NCO1 | NCO2 | M2 | M1 | B1 | R1 | R2 | R3 |
| 1-C | 60 | 100 | ||||||
| 2-C | 30 | 100 | ||||||

| 4 | 25 | 90 | 10 | |||||
| 5 | 35 | 70 | 30 | |||||

一些粘着剂组合物的固化测量如下。混合展示于上表中的成分，并且接着将混合物加热到50℃。在保持在50℃下的同时，如上文所描述测量混合物的粘度(Visc50)。结果如下：
50℃下的粘度(mPa.s)对比时间(分钟)
对前述资料的检查展示，从0到60分钟，粘着剂组合物1-C的粘度以恒定速率增加。因为粘度增加的速率恒定并且极小，所以得出以下结论：组合物1-C将不在任何合理时间内达成合乎需要的高粘度，并且因此在60分钟之后不对组合物1-C进行进一步测量。
组合物3展示比组合物2-C更合乎需要的行为或粘度对比时间。组合物2-C的粘度增加速率相对恒定，并且因此认为，组合物2-C将需要极长时间来实现高达10,000mPa.s的粘度。相比之下，组合物3的粘度展示自身恒定增加的增加速率。因此，虽然组合物2-C具有相对较低粘度(低于500mPa.s)持续超过60分钟，但组合物2-C也在仅120分钟内实现极高粘度(高于10,000mPa.s)。
