Conversion Coating for painting zinc, painting aluminum & painting

galvanized metal & prevents  zinc corrosion and is RoHS Compliant


Sanchem’s SafeGard® CC-3400 and SafeGard CC-8400 are RoHS compliant chromate-free chemical conversion coatings that leave an electrically conductive  clear or gold protective surface treatment on aluminum, zinc, zinc plated or galvanized steel.  You can use this corrosion resistant metal pretreatment to have excellent adhesion with paints, powder coatings and adhesives. Sanchem’s metal pretreatments can be cold applied, hot applied, heat curable or electrolytic applied conversion coatings.  Chromate-free SafeGard CC-3400 is Qualicoat approved and Sanchem is ISO-9001.2000 certified.

Why you should use SafeGard CC-3400 on zinc plating, zinc die cast & galvanized metal:


  • Meets ASTM Standard B-940-05, Non-Chromate Conversion Coatings on Zinc Surfaces.                 
  • Salt Spray ASTM B-117: Over 300 hours 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 conversion coating.

An overview of non-chromium conversion coatings (PDF)

SafeGard 3000 - a non electolytic anodized oxide coating. The Naval Air Development Center tested this chromate-free metal surface treatment to the Mil-C-5541 specification.  Their conclusion was that SafeGard CC is the best non chromate conversion coating terms of paint adhesion and corrosion resistance.

Who has tested and Approved Safegard CC?

Touchstone Systems & Services Inc - SafeGard CC-3400 Passed General Motors tests on a 360 cast aluminum alloy Part#H878: Initial Tape Adhesion, Humidity and Tape Adhesion, Neutral Salt Spray & Corrosion, Dime Scrape, Thumbnail Hardness, Gasoline Resistance Dip, Gasoline Resistance Puddle, Oil Resistance Dipping and Chip Resistance Testing per GM 9508P Method B @ -30b.

Stork Technimet Inc: Passed 168 hours Salt Spray testing per Mil-C5541E on aluminum alloy 7075 following ASTM B-117.  Stock Technimet is an ISO-Certified lab.

GE qualification performance testing –SafeGard CC-3400 is Approved.  Tests ran included: Dry Oxygen Environment Test, Storage/Shipping Environment Test and Material Compatibility Test. Conclusion: The conversion coating Sanchem SafeGard CC-3400 is a suitable replacement for Hexavalent Chromate Conversion Coating

Sanchem’s SafeGard CC is Qualicoat Approved - Testing Procedures this product passed for approval included: Resistance to boiling water Method2 (Pressure Cooker), Constant climate condensation water test, Machu Test according to QUALICOAT Specifications, Acetic acid salt spray test according to ISO-9227, Adhesion according EN ISO-2409, Cupping test EN ISO-1520, Bend Test EN ISO-1519 and Impact Test ASTM D-2479.

3M’s Scotchlite Reflective Sheeting for Traffic Signs – Safegard CC-3400 is 3M approved.   3M required that a hexavalent chrome pretreatment be used under 3M’s Scotchlite Reflective Sheeting for Traffic Signs.  3M required that SafeGard CC-3400 pass both a 6 months outdoor exposure testing at LaQue Corrosion Services in Wrightville Beach, NC and Neutral Salt Spray testing which was performed at Phoenix Chemical laboratory in Chicago, IL using both 6061 & 5052 aluminum alloys.

Alloy Wheels International @ Kent laboratory Report – Wheel Type T498 - SafeGard CC-3400 meets their paint pretreatment requirements.  Tests Run on painted wheels: CASS(Copper-Accelerated Acetic Acid Salt Spray) , Water Soak FLTM B1 104-01, ambient road gravel, -10c road gravel, neutral salt spray 1000 hours & thermal shock FLTM B1 107-05.  

Why you should use SafeGard CC-3400 on zinc plating, zinc die cast & galvanized metal:


  • Meets ASTM Standard B-940-05, Non-Chromate Conversion Coatings on Zinc Surfaces.                 
  • Salt Spray ASTM B-117: Over 300 hours zinc plating and over 300 hours zinc castings (when used with SafeGard CC-4000 seal).   
  • Chemically and UV stable.

Magnesium is a very reactive metal so salt spray tests according to ASTM B-117 are not generally run.  The corrosion resistance of chromate conversion coated magnesium is quite small to begin with and there are no specified bare salt spray corrosion tests for magnesium.  Here are Salt Spray testing (ASTM-B117) results:
