You can get both the golden color you remember and clear with SafeGard CC 3400, a chromium-free electrically conductive conversion coating available for direct purchase from Sanchem. Not only is SafeGard CC-3400 is electrically conductive, it enhances paint adhesion, and prevents corrosion due to humidity and salt spray. SafeGard CC-3400 is a multi-metal product, it can be used on aluminum, magnesium and zinc. SafeGard CC is approved by many European electronics firms as the preferred treatment for finishing aluminum surfaces and getting the golden chromate color without using chromate, to meet RoHS requirements.
Why you should use SafeGard CC-3400 on aluminum, zinc plating, zinc die cast & galvanized metal:
- Salt Spray ASTM B-117: Over 300 hours on aluminum, zinc plating, galvanized steel and over 300 hours zinc castings.
- Easy to use and monitor
- Conductive
- Excellent paint pretreatment
- Electrically conductive
- Excellent corrosion resistance: humidity, salt spray and UV Stable
- Paint adhesion: Passes both wet tape & dry tape tests. (Qualicoat Approved)
- Easy to use and maintain, no sludge will builds up in tank.
- Perfect for high temperature applications –doesn’t breakdown when heated.
- RoHS Compliant - SafeGard CC is completely chromium free.
- Economical – one gallon of SafeGard CC concentrate can treat 10,000 ft2 of aluminum!
- Heating will not affect chromate-free SafeGard CC conversion coating. This is due to the fact that SafeGard CC reacts to the aluminum and zinc surfaces at the molecular level it is not a surface coating. It is a true electrically conductive conversion coating.
- The Boeing Company St Louis, MO: – Passed all test requirements. Sanchem’s SafeGard CC-6100 with SafeGard CC-3400seal#2.
