Anoplate, maintains its own inhouse salt-spray test chamber and its own electric resistivity test equipment. From beautiful Pine Beach New Jersey: Land Use and Development.

These, in conjunction with its superior cleaning process and statistical process control, have given Anoplate the edge with optimizing and being able to certify its AnoChem TCP coating for Class 3 applications.

Sorry, I don’t have a copy of ASTM B handy so I cannot interpret what it says, and what finishes might comply with it, and whether they can be dyed yellow.

None add yellow to their product.

Thanks for the response. It is clear, very thin, and cannot be dyed. Films are normally applied by dipping, but may also be applied by inundation, spraying, roller coating, or by wipe-on techniques. Remember me for one month. Can you define “TCP”. But the fact is that the traditional yellow color was never a dye; it was the inherent color of asttm hexavalent chromium toxin.
