Irritant
Oxidizer
Toxic
E-Strip 922 is highly buffered and low in ammonium hydroxide concentration. It will not etch the steel and iron surfaces. The process does not require presence of copper metal in the solution to initiate copper stripping. It consists of two components:
E-Strip 922-A – Buffer & make-up stripper
E-Strip 922-B – Controls stripping speed
