FAQ/TCP-HF Question 9

Q:
Is there a difference in adhesion between hexavalent and trivalent chromates?

 
A:
CHEMEON TCP-HF provides adhesive bonding layer on the metal surface at least as good as hexavalent chromate does. Dry tape, wet tape, and filiform corrosion (scribed and top-coated CHEMEON TCP-HF panels) under neutral salt spray were mainly tested for the adhesion properties.
