TWO-STEP PROCESS FOR RAPID STRUCTURE REPAIR

This invention relates to a two-step process for rapidly repairing structures, which utilizes (a) a water-based emulsion component in the first step, and (b) a polyisocyanate-terminated pre- polymer component in the second step, such that the mixture of (a) and (b) cure in the presence of moisture....

Zusammenfassung:	This invention relates to a two-step process for rapidly repairing structures, which utilizes (a) a water-based emulsion component in the first step, and (b) a polyisocyanate-terminated pre- polymer component in the second step, such that the mixture of (a) and (b) cure in the presence of moisture. La présente invention concerne un procédé en deux étapes permettant de réparer rapidement des structures, consistant à utiliser (a) une émulsion à base d'eau dans la première étape et (b) un prépolymère à terminaison polyisocyanate dans la seconde étape, de façon que le mélange formé par (a) et (b) durcisse en présence d'humidité.
