A unique formulation of 93% pure zinc metal as a liquid coating, ZRC 221 is a low VOC version of our famous ZRC Cold Galvanizing Compound.  Same great performance of original ZRC with a reduced VOC content for restricted areas and LEED building projects. The ZRC difference is made possible by ZRC's high zinc content (93% by weight in the dried film) of “ultra pure” (ASTM D 520 Type III) zinc dust, ensuring that more metallic zinc is available for superior galvanic protection against corrosion. This high purity zinc dust is compounded with a tenacious non-encapsulating binder using a highly controlled trade secret process in our state-of-the-art manufacturing facility. The result is a self-healing galvanic film that does not require sandblasting for most applications, providing both up-front labor savings and extended longevity of corrosion protection.
