The pot life of 2K polyurethane can be as short as 3 or 4 hours. Once a urethane coating is fully cured the film is inert and is not dangerous to the environment or the occupant of the space. The benefits, in general, are superior durability and higher solids, so you can obtain high levels of physical performance and sometimes get away with using fewer coats. But formaldehyde is emitted from the finish for a considerable time after application, while isocyanates become totally reacted with the rest of the finish very quickly.Though manufacturers have been working hard to reduce and even eliminate (in some cases) the formaldehyde in their catalyzed finishes, most of these finishes still contain some formaldehyde.This is a big reason for 2K polyurethanes being more popular in Europe, where catalyzed finishes arent even allowed in some areas because of the health risks to consumers.Of course, both the isocyanates and the formaldehyde pose health risks to spray operators, but in neither case is this true if he or she is working in a proper spray booth and wearing an appropriate respirator.As with any case when trying a new and unfamiliar finish, be sure to read all data sheets and maybe even talk to a manufacturers representative if you do decide to try two-part polyurethane.
