Alodine® EC2TM
Alodine® EC2TM
Hardness and Wear Resistance?
Alodine® EC² is thousands of times harder and more flexible then paint.

Superior gravelometer results! |
Heat and Chemical Resistance
Alodine® EC² can withstand temperatures up to 600ºC. It is impervious to fuel and fuel vapor, powertrain lubricants and oil, and ethylene glycol. It is also resistant to exhaust gases.

| Hot & Cold Solvent borne paint strippers | 12 microns (0.0005") | 30 days | No effect or attack |
Alodine® EC² also prevents galvanic coupling of dissimilar metals.
Many parts and components can be made out of aluminum rather then steel thus saving weight without sacrificing performance.
Flexibility Crosshatch followed by impact (metal fractured)
Furthermore, the economic advantages, due to the high performance and simplicity of the process is clear. With only two process steps, production is efficient and lean, minimizing time, floor space, and cost. With no toxic substances, expensive regulatory costs can also be reduced or eliminated. However, the most important are the unique properties of the Alodine® EC² process.
