Isocyanates have been used for many years as crosslinkers in coatings, foams, and elastomers. The desirability of one pack coatings systems for many end use applications has led to the development of “blocked” isocyanate crosslinkers. Cure in these materials follows a two step mechanism [1,2] consisting of thermal deblocking of the blocked isocyanate to give free isocyanate followed by reaction of free isocyanate with a reactive functionality, often hydroxyl, to provide the actual chemical cross1inks.
