Chem film

Chem film is a non-anodic protective coating.  Chem film {aka   Alodine, Iridite, or Chromate Conversion} is a microscopic thin film commonly prescribed on aluminum to:

• Provide an Excellent surface prep for paint
• Aid in Corrosion Resistance
• Impose desired Electrical 'Resistance' characteristics,  (commonly prescribed for Radio and Amplifier cabinets.)

SPECIFICATIONS & CERTIFICATIONS:  Alodine Methods and Properties are described in Mil-C-5541 (Now AMS-C-5541)  and AMS-A-2473.   Iridescent Gold and Clear are available. We follow the format and guidelines of those documents. The common Spec Call-outs are

• Class 1A:  Standard for Maximum Protection
• Class 3:   Minimum thickness for reduced electrical resistance
