Peroxy-Sulfuric Etching Module
Getting Things Ready/Filling
- Put on your acid proof smock and gloves and a facemask (or a pair of safety glasses with full side shields).
- Remove the tank cover plate and set aside in a clean, safe place.
- Make sure that the drain valve is CLOSED and screw cap is in place.
- Add 5 gallons of deionized water to the tank and pre-heat to140°F (60°C).
- Slowly add the cupric sulfate crystals to the tank, stirring constantly until the crystals are completely dissolved. (You really do not need to perform steps 4 " 5 since you will be forming plenty of cupric sulfate when you start etching. However, adding a bit at the beginning will make the etching process more linear and predictable.)
NOTE: Be VERY careful not to hit the heater or the float switch while stirring.
- Using the recipes below, CAREFULLY add the sulfuric acid and MF 244 stabilizer to the tank.
- Replace the tank cover plate and continue filling the tank with deionized water until the solution just contacts the stainless steel ribs on the bottom of the tank cover plate.
- Reduce the temperature setting on the controller to 115°F and allow the system to come up to temperature.
- Using the air switch on the control panel, cycle the air agitation a few times stir up the bath and dissolve any reluctant copper sulfate crystals that might remain.
