Description
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 (Hot Dip Galvanizing)
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
