Product Usage

forGalvanized sheet, zinc, aluminum and steelUsed in surface coatings to enhance adhesion between metals and paint or powder coatings.

 

 

advantage

          

  1. Free of heavy metals, nitrogen and phosphorus
  2. No COD No BOD
  3. Phosphating residues free from phosphate series and other wastes
  4. No sewage treatment required
  5. Comply with EU ROHS and WEEE directive requirements

 

Process performance

  

1. The process is simple and the operation is convenient

2. Corrosion resistance between iron and zinc series phosphate processes, after printing, the salt spray test time can reach 300-500 hours

3. Pass the 50Kg·cm impact test, no paint falling off on the front and back

4. Cross-cut test reaches 0

 

u Process description

  • Ø Degreasing: It is best to use a suitable alkaline degreasing system. Please refer to the relevant product specifications;
  • Ø Water flushing: continuous overflow should be maintained to prevent pollution;
  • Ø Rinse with deionized/reverse osmosis water: the workpiece is rinsed before nano-phosphating. Continuous overflow should be maintained to prevent contamination;
  • Ø Nano conversion: stay within the recommended parameters;
  • Ø DI/RO water flushing: continuous overflow control conductivity less than 25us/cm;
  • Ø Drying: It is recommended to dry completely. Dry in an oven indirectly heated to 110 to 170°C for 10 to 20 minutes.
product description

 

 

 

1) IC-2011 is a coupling agent-based chemical that cleans the surface of metal materials and forms a complete nano-coating. Form conversion coating on the surface of steel, zinc, aluminum, no heavy metal, no phosphate.

2) IC-2011 can significantly improve the corrosion resistance of the metal coating and prolong the corrosion time.

 

3) The corrosion resistance of IC-2011 is greater than or equal to the iron phosphate/polymer blocking and chromium-free after water washing. Suitable for normal temperature spraying or dipping treatment process, deionized water washing treatment.

4) IC-2011 can be matched with various coatings.
