Application

CE-200 solution can be used to etch out the copper residue or foil from the chemical vapor deposited (CVD) graphene or carbonated films by immersing the substrate with the nanomaterial into the etchant solution for 30 min.
It is ideal for spray etching of copper. Ferric chloride based Cu etchant with etch rate of 0.5 mil/min @ 40 °C.
