Dichromate seal for anodizing aluminium
+++
HI!
WE ALREADY HAVE A SMALL SET-UP FOR ANODIZING AND WE LIKE TO DO
DICHROMATE SEAL ON PARTS (LOOKS LIKE GREEN-YELLOW).
WHERE DO I CAN FIND INFORMATION ABOUT THIS PROCESS?
THANK YOU,

The book The Surface Treatment and
Finishing of Aluminum and Its Alloys by S. Wernick, R. Pinner,
P.G. Sheasby has the info you need.
