Rhodium-catalyzed addition-cure coatings are unique to Dow Corning, and the
cure chemistry is exceptionally robust.
Rhodium is inert against all commonly used adhesives, and it is relatively
difficult to poison the catalyst.
Rhodium-catalyzed coatings are less sensitive to substrate inhibition than
platinum-catalyzed coatings. However, they do cure more slowly and at a higher
temperature, making them unsuitable for temperature-sensitive substrates. These
coatings are also unsuitable for food-contact applications.
Rhodium-catalyzed coatings have been successfully applied to solventless
delivery systems.
