DACROMET®

DACROMEt®


DACROMET®, is the leading inorganic coating commonly specified in the wind turbine, heavy truck, marine, agricultural, construction equipment and aerospace industries. A water-based, VOC-compliant coating, DACROMET® is comprised mainly of overlapping zinc and aluminum flake in an inorganic binder.

Four-Way Corrosion Protection

  • Barrier Protection: Overlapping zinc and aluminum flakes provide an excellent barrier
  • Galvanic Action: Zinc corrodes to protect steel
  • Passivation: Metal oxides slow down the corrosion reaction of zinc and steel
  • Self-Repairing: Zinc oxides and carbonates migrate to the damaged area to repair and restore the coating

Dacromet® Advantages

  • Thin: DACROMET® is 5-7 microns and DACROMET® L is 7-9 microns
  • Hydrogen Embrittlement Free Process: Coating does not require acid pickling or electroplating
  • Bimetallic Corrosion Resistant: Aluminum flake eliminates the typical bimetallic cell of zinc coatings
  • Solvent Resistant: Inorganic nature causes it to be resistant to organic solvents
  • Heat Resistant: Maintains corrosion resistance even following an intermittent heat shock
  • Conductive: Concentration of metallic flake allows an electrical current to be passed
  • Salt Spray Resistance: 1,000 hours
  • Better Than Pure Zinc: 3 times greater corrosion protection than pure zinc

Environmental Benefits

  • No Toxic Metals: Free of nickel, cadmium, lead, barium and mercury
  • Water Based: Free from dangerous solvents
  • VOC Compliant: Under EPA RACT requirements

Versatile Applications

Matenaer applies DACROMET® using the rack application process (dip-drain-spin, spray) following an alkaline and/or mechanical cleaning cycle. Coating thickness can be varied by altering elements in the application processes. DACROMET® is cured at 610°F PMT (part metal temperature), which must be maintained for 15 minutes.
