Abstract:
A method for calculating the amount of solution components to add to an advanced coating removal (ACR) stripping solution in a coating removal stripping bath to replenish and recover stripping potential. The stripping effectiveness may be restored by the addition of only the primary acid of the composition of acids of the stripping bath and fresh water, in an amount necessary to restore the stripping solution to its original density.
