TCP-HF Question 13
Question: Can CHEMEON TCP-HF Touch-Up Pen be used on part previously processed with hexavalent based chemistry, for example Alodine 1200?
Answer: CHEMEON TCP-HF Touch-Up Pen can be used on parts that were previously processed with hexavalent chemistry. Of course, in order to ensure good performance, the area to be applied should be free of any oils and grease and totally clean.
Question: Is there any chance that the pen might reactivate the existing Hex on the surface and contaminate the tip of the pen?
Answer: The presence of trivalent chromium will not "reactivate" the surface or otherwise cause the hexavalent chromium to spread on the part or pen tip.
