Corrosion resistance after 1000 hours of salt water spray: Dacromet®, hot-dipped galvanized, mechanically galvanized.
Four-Way Corrosion Resistance
- Barrier Protection Many overlapping zinc and aluminum flakes provide an excellent barrier
- Galvanic Action Zinc corrodes to protect steel
- Passivation Metal oxides in matrix slow down corrosion reactions of zinc and steel
- Self-Repairing Damaged areas in the coating fill with zinc oxides and carbonates
Due to the concentration of aluminum within the coating, good bi-metallic corrosion resistance with aluminum is accomplished
When DACROMET® is cured on the metal surface, the coating becomes inorganic, and thus resistant to solvents, gasoline, brake fluids, etc.
The high concentration of metallic flake enables DACROTIZED® parts to be electrically conductive
Hydrogen Embrittlement Free
The absence of acids or electrolysis in the coating process assures freedom from Hydrogen Embitterment, which is commonly associated with the electroplating process
DACROMET® is a base for most paints, including electro-deposited paint
