Magnavis® 7C is a black dry powder concentrate ideally suited for use on light colored surfaces for optimum color contrast. 7C may be suspended in either Carrier II Oil Vehicle or in water. When water is used as a vehicle, conditioning agents such as WA-2B (1-1/3 oz./gal.) or WC-1 (2% by volume) are required. The conditioning agents improve particle suspendibility and mobility as well as part surface wetting and nominal corrosion inhibition.

Magnavis® 7C Black powder is generally used at a concentration of 1-1/4 oz./gal. (9.4 g/l).
