Many plating shops want to switch to TCP, so I think it will be ever harder for you to continue to make your parts look like they are carcinogenic when they are not: None add yellow to their product.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory requirements prior to use. It is clear, very thin, and cannot be dyed. I have just checked today with several chem. AnoChem TCP left has a clear, bright finish with b9221 blue iridescence and should not be mistaken that the part is untreated.

It is a trivalent chromium conversion process. Land Use and Development. Films are normally applied by dipping, but may also be applied by inundation, spraying, roller coating, or b9211 wipe-on techniques. But the fact is that the traditional yellow color was never a dye; it was the inherent color of the hexavalent chromium toxin.

AnoChem TCP replaces hexavalent chromate conversion coatings used for aluminum alloys without sacrificing corrosion resistance, electrical contact resistance or organic topcoat adhesion properties while meeting regulatory requirements of ROHS, WEEE and ELV legislation.

Traditional hexavalent chromium right has its characteristic gold iridescence. Coatings shall adhere to specified electrical resistance, adhesion, and corrosion asgm requirements. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. This abstract is a brief summary of the referenced standard. This may be what your vendors have switched to.

AnoChem TCP

The type of conversion coating depends on the composition of the solution and may also be affected by pH, temperature, duration of the treatment, and the nature and surface condition. AnoChem TCP should be applied where conductivity, paintability or corrosion resistance are required on adtm substrates. Remember me for one month.
