PROPERTIES

Chromate conversion coatings (Chemfilm) are a varying group that can be done as a stand alone finish, used by itself, or as a secondary post finish treatment, used over a metal plating. Chemical Film on Aluminum, also called by proprietary names of Alodine or Irridite, is a thin, clear or yellow conversion coating used as a primer for paint, general protection to prevent aluminum from oxidizing, or used in conjunction with masking of an anodized finish for conductivity properties.

Elite Metal Finishing offers yellow/gold hexavalent  and clear RoHS compliant Chemfilm.

Chromate Conversion Coatings Features:

  • On aluminum or mixed metal assemblies that can’t be anodized

FAQs about Metal Finishing

Anodizing is an electrochemical conversion process that forms an oxide film, usually on aluminum, in an electrolyte (chemical solution). Compared to Type II anodizing, the coating applied via Type III anodizing is usually thicker, done at a lower temperature, and more expensive. However, there are benefits to Type III anodizing, such as a thicker coating (typically between 0.001 and 0.002 inches) that tends to be more durable and abrasion resistant.

  • Anti-static / ESD control – coatings used to minimize static electricity in sensitive environments.
  • Chemical resistant – coatings which resist acids, alkalis, oils, and general chemicals.
  • Conductive – coatings used to form an electrically-conductive layer.
  • Dielectric – coatings made from nonconducting materials used in optical applications. High-reflection coatings consist of a stack of alternating layers of high-and-low refractive-index materials. Each layer in the stack has an optical thickness of a quarter-wave at the design wavelength.
  • Corrosion inhibiting – coatings which prevent moisture from reaching the metal or underlying substrate, or provide a sacrificial layer.
  • EMI / RFI shielding – coatings provide shielding from electromagnetic interference (EMI) or radio frequency interference (RFI).
  • Flame retardant – coatings are flame-retardant in accordance to Underwriters Laboratories, Inc. (UL) Flame Class 94V-0, or other equivalent ISO standards. These materials reduce the spread of flame or resist ignition when exposed to high temperatures. They also insulate the substrate and delay damage to the substrate.
  • Heat resistant – coatings resist damage from heat, or are formulated for use in high-temperature environments.
  • Protective – coatings are designed to protect substrates and surfaces.
  • Touch-up – coatings are used to repair and match the original coating where it has been damaged by scratching, corrosion, abrasion, erosion, scuffing, denting, chipping, delaminating, or other processes.
