ONE-STEP PROCESS FOR RAPID STRUCTURE REPAIR

This invention relates to a one-step process for rapidly repairing structures. The process uses a binder comprising a polyisocyanate-terminated pre-polymer containing a divalent metal catalyst, an acid chloride retarder, and preferably a tertiary amine catalyst, which cures in the presence of moistu...

Zusammenfassung:	This invention relates to a one-step process for rapidly repairing structures. The process uses a binder comprising a polyisocyanate-terminated pre-polymer containing a divalent metal catalyst, an acid chloride retarder, and preferably a tertiary amine catalyst, which cures in the presence of moisture. L'invention concerne un procédé permettant de réparer rapidement des structures en une étape. Ledit procédé permet d'utiliser un liant comprenant un prépolymère à terminaison polyisocyanate qui contient un catalyseur de métal divalent, un retardateur de chlorure d'acide et, de préférence, un catalyseur d'amine tertiaire qui durcit en présence d'humidité.
