EL-O-MATIC STANDARD CORROSION PROTECTION SYSTEM
Description
The corrosion protection system of standard El-O-Matic E&P series pneumatic actuators consist of the
following treatments or materials:
1 De-greasing
Stainless steel fasteners 2 Powder coating
3 High grade & hard anodized aluminum pinion
4 Stainless steel or Deltatone

Materials
Application
Option
All aluminum parts are de-greased before the powder coating is applied by washing with an alkaline
solution to assure the best bonding between the aluminum surface and the coating.
- Polyester non-TGIC based powder coating for exterior use.
- The powder coating is applied cold using automatic electrostatic spray equipment and is cured at
minimum 190°C (374°F) offering excellent anti color fade and weather resistance.
- The powder coating thickness is 1.5 mm (37 microns) minimum, and 2 mm (50 microns) average.
- Good resistance against most chemical bases, acids, solvents, alkalis and oils at normal temperatures.
- Excellent exterior mechanical durability.
- The coating has passed a salt spray test according to ASTM B117 for 500 hours. The powder coating is
virtually solvent free, and therefore environmentally friendly.
Actuators with high grade & hard anodized aluminum pinions, passed a 500 hours salt spray test.
Optional stainless steel pinions are available for a higher corrosion resistance.
