VISUETCH REPLENISHER is used in conjunction with Hydrochloric Acid
(aka Muriatic Acid) to replenish Cupric Chloride etchers controlled by the OE
Visuetch. When Copper is etched in Cupric Chloride etchant, Cuprous (Cu+)
Copper is created in the etch solution. This must be regenerated back to Cupric
(Cu++) Copper virtually immediately, or etch speed will fall dramatically.
VISUETCH Replenisher converts Cuprous to Cupric Copper, and allows
continuous, steady etching.
