Material Notes:

Description: CHO-SHIELD® 579 coating is a two component, silver-filled, highly conductive epoxy paint designed to provide EMI shielding when applied to a dielectric substrate. This coating was specially developed as a variant of CHO-SHIELD® with a lower VOC rating. CHO-SHIELD® 579 dries to the touch in less than 1 hour at room temperature and attains full chemical resistance after 1 week at room temperature. However, the best electrical properties are achieved by curing at elevated temperatures.Information provided by Chomerics
