What effect does tarnish on copper have on product parameters?

This is one of the more common questions that we are asked. Customers are primarily concerned with adhesion and surface resistance. Does the surface resistance increase with increased tarnish levels?  Will epoxy adhere to a tarnished copper surface? To try and provide an answer, we undertook some elementary evaluations of copper samples with varying levels of tarnish identified using the L*a*b* color space coordinates. For those unfamiliar with the L*a*b* system, the short answer is that every color can be defined in terms of 3 numbers.  The first number, “L”, is for lightness which ranges from 0-100, with 0 being black and 100 being white. Everything else is shades of gray. The second number, “a”, is either positive (Red) or negative (green). The third number, “b”, is either positive (yellow) or negative (blue).  That is it in a nutshell. All shades of copper and its tarnish can be defined in this way.

DEXMET CORPORATION TO OFFER Victrex APTIV® PEEK™ FILM BASED EXPANDED MESH PRODUCTS FOR HIGH PERFORMANCE DEMANDS OF THE FILTRATION INDUSTRY

Wallingford, CT – (November 29, 2011) – When Dexmet Corporation, a manufacturer of precision expanded metal foils (MicroGrid®) and polymer films, wanted to add a high performance polymer to its PolyGrid® portfolio, it chose one of the highest regarded performing thermoplastics in the world, Victrex APTIV® film made with VICTREX® PEEK™ polymer.  Utilizing specifically designed proprietary equipment and processes, Dexmet performs an expansion procedure on the high performance polymer to produce a diamond configured, open area mesh product for filtration applications.  Providing all of the outstanding properties of VICTREX PEEK polymer in a versatile thin film format, APTIV film was selected for its superior combination of mechanical strength, chemical and high temperature resistance. “While it technically falls under our high temperature PolyGrid product line,” said Ken Burtt, VP of Sales and Marketing at Dexmet, “APTIV film provides much more than just high temperature capabilities.  It also has great chemical compatibility as well as mechanical strength that may be required for certain filter applications in harsh environments making it more of a ‘high performance’ PolyGrid material.”
