Abstract
Description
イソシアネート成分は、少なくとも1つのイソシアネートと、少なくとも1つのポリオールと、分枝鎖アルカンジオールとを含む反応体(「プレポリマー反応体」)の反応生成物である少なくとも1つのイソシアネートプレポリマーを含む。
無溶剤接着剤組成物は、少なくとも1つのポリオールと分枝鎖アルカンジオールとを含むポリオール成分をさらに含む。
例示の実施例(「IE」)及び比較例(「CE」)で使用するための原料を以下の表1に詳述する。
実施例組成物を使用するコーティング及びラミネーションはNordmeccanica Labo−Combi 400ラミネート機で行う。ニップ温度は、全ラミネーションプロセス中、100m/分の速度において、40℃に保つ。コーティング重量は1.8〜2.0g/m2である。コーティング後、試験前に、ラミネートフィルムを、室温(23〜25℃)またはオーブン中において高温で硬化させる。
