Two new polymer-based seals for anodized Aluminum: Non-Hazardous, No metals

November 18, 2020

Q. I am currently developing 2 seals for anodized Aluminum that have no metals. The 1st will pass dye stain every time. This would be great for decorative Type II anodizing. The 2nd has added PTFE but at a low concentration. The PTFE will stay dispersed and suspended in this matrix, greatly reducing the cost of this PTFE seal. This would be good for jobs that need lubricity or hardcoat. They both will operate at 5% by volume and a pH of about 9 - 9.5 for 15 minutes. They are really outside the box but both work very well. For Architectural or automotive more testing needs to be done. The question: Is there a market for a product like these out there?

A. Hi Bill. We're happy to post your inquiry and see what kind of responses you get to the question of whether there is a market for such products! And nice to meet an old hand :-)

sidebar But apologies, we must be careful that postings don't serve as free ads or offer commercial benefit (why?)

Please check out the half-dozen or so 'groups' about plating, anodizing, and metal finishing on Facebook, and see if you agree with my assessment that all of them degenerated into spamfests, unusable as technical forums or places of camaraderie -- just like happened to the wonderful sci.chem newsgroups years ago. So we can't print your contact info or that of any responders expressing interest. I hate to make life difficult for people, but can't make it impossible for myself, our advertisers, and our readers :-(

Luck & Regards,
