META-STRIP 151 is the ultimate stripper for removing electroless nickel from steel, brass, and copper. This revolutionary product will not sludge, will not attack copper, and has exceptional life compared to preexisting technologies. META-Strip 151 strips both high and mid phosphorous EN with ease and continues to perform well to 2-4 oz/gal Ni. The META-STRIP 151 process consists of two concentrates, META-STRIP 151-P and META-STRIP 151-L. META-STRIP 151-P and META-STRIP 151-L are used together for stripping most nickel deposits. This process is cyanide-free.
