Delta-Tone 9000 - Application and Performance

Overview   |   Properties   |   Application and Performance


DELTA-Tone 9000 is used as a base coat on ferrous components processed in a basket or on jigs.

Products processed in a basket by dip-spin:

Bolts, Nuts, Dowels, Clips, Clamps, Tension Springs, Pins, Small Castings as well as other fixing elements for the automotive industry, building industry, Steel construction, and many other industries

Products processed on jigs by dip-drain or spray:

Larger components such as stampings and pressings, large compression springs, chains guide rails, mounting rails, fixing plates trailer couplings connectors, materials handling components etc.


All the more well-known processes that have no detrimental effect on parts may be used. Alkaline degreasing is a typical example.


All the more well-known chemical pickling processes can be used unless they are detrimental to the parts in question. Shot blasting can also be used on suitable components.


Coating Thickness: The corrosion resistance of Delta-Tone 9000 will increase with increasing coating thickness and number of coats, it exhibits a self healing effect caused by the migration of zinc corrosion products into damaged areas.

  1. Standard protection - salt spray test according to ASTM B117 over 250 h. 20 to 26 g/m² dry coat weight are equivalent to 6 and 8µ dry coat thickness
  2. Improved protection - salt spray test according to ASTM B117 over 600 h. 32 to 38 g/m² dry coat weight are equivalent to 10 and 12µ dry coat thickness

Delta Tone 9000 can be used in areas exposed to heat up to 150°C and is resistant to organic solvents. Delta Tone 9000 provides bimetallic corrosion resistance when used on parts assembled to aluminium.

This information is based on our current knowledge and our interpretation of the specifications.

Corrosion protection is dependent upon the build-up coats, geometry and type of application.
