A two-package sprayable coating composition having a binder that comprises, in one package, a chemical compound with functionality "A" and, in another package, a chemical compound with functionalities "B" and "C". Functionalities "A" and "B" react rapidly to build molecular weight without crosslinking while functionality "C" reacts with the reaction product of "A" and "B" or with "A" or with both, which reaction occurs more slowly than reaction of "A" with "B", to form a crosslinked film at cure. |
