ACTIVATOR XF is used for etching in one step unalloyed or low‐alloyed steels that may be heat treated up to 1800‐1900 MPa like
SAE 4340 steel. It is applied using the standard BRUSH electrolysis process, or its son process DALISTICK (see FTDA6 in this case).
The solution is designed to eliminate various surface impurities, oxides and precipitates for ensuring a good adhesion of a metal
layer on the surface. It is applicable also for dissolving locally damaged cadmium or zinc‐nickel coats.
Before Brush cadmium or zinc‐nickel plating on high strength steels, it contributes to pass Hydrogen embrittlement tests
according to ASTM F519 standard on unbaked parts.
