This process is almost colorless and cannot be dyed. Land Use and Development. It is clear, very thin, and cannot be dyed.

Coatings shall adhere to specified electrical resistance, adhesion, and corrosion resistance requirements.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. This specification covers the requirements relating to rinsed and non-rinsed non-hexavalent chromium conversion coatings on aluminum and aluminum alloys intended to retard corrosion; as a base for organic films including paints, plastics, and adhesives; and as.

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. Enter your account email address to request a password reset: AnoChem TCP should be applied where conductivity, paintability or corrosion resistance are required on aluminum substrates. Traditional hexavalent chromium right has its characteristic gold iridescence. This may be what your vendors have switched to.

Are you sure you want to empty the cart? Maybe somebody can add a UV trace to the coating similar to parylene conformal coating–there is a UV trace added. I don’t think you need to give up on ASTM compliance, but should consider getting away from the gold colored dye. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Films are normally applied by dipping, but may also aastm applied by inundation, spraying, roller coating, or by wipe-on techniques. 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. Coatings are categorized sstm four classes according to corrosion protection and finish. 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: Link to Active This link will always route to the current Active version of the standard.

This abstract is a brief summary of the referenced standard. Anoplate, maintains its own inhouse salt-spray test b9921 and its own electric resistivity test equipment.

ASTM B921 – 08(2018)

This specification covers the requirements relating to rinsed and non-rinsed non-hexavalent chromium conversion coatings on aluminum and aluminum alloys intended to retard corrosion; as a base for organic films including paints, plastics, and adhesives; and as.

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. This abstract is a brief summary of the referenced standard. Anoplate will be closed December 24th, 25th, 31st and January 1st.

Non Hexavalent Chromium Conversion (Clear)

Coatings are categorized into four classes according to corrosion protection and finish. We work in partnership with some of the largest and most respected names in industry. AnoChem TCP replaces hexavalent chromate conversion coatings used for aluminum ashm without sacrificing corrosion resistance, electrical contact resistance or organic topcoat adhesion properties while meeting regulatory requirements of ROHS, WEEE and ELV legislation. Remember me for one month.

AnoChem TCP is an excellent solution for the following applications: This is the only non-hex process that meets the MIL spec, and so I suspect that your vendor switched to this, and I have no reason to question your vendor’s statement.

Register for a trial account. My question is, would they be eliminating the gold tint strictly due to environmental concerns or as an easy differentiation between finishes and will the finish still be in compliance with ASTM B? Both impart a clearly visible blue color to the trivalent chromate conversion coating and do not reduce salt spray testing hours. If you like to setup a quick demo, let us know at support madcad.
