Zusammenfassung:	The present invention relates to moisture curable reactive adhesive compositions containing a visual indicator and methods for using these compositions. Specifically, the invention relates to a two part moisture curable reactive adhesive system, where one part consists of a prepolymer with moisture reactive groups and the second part consists of catalyst, a visual indicator and water. The presence of the indicator allows the combination of the two part system to be visible to the naked eye. The visible indicator ensures that the two part system is combined uniformly and completely to a desired substrate, but it does not interfere with the crosslinking reaction.
