The patented three-part SermaLon^® coating system was developed primarily to provide anti-fouling and corrosion protection to driven compressor components and industrial gas turbine components exposed to wet chloride attack, as well as steam turbine components.

The SermaLon coating system consists of:

• An aluminum-filled chromate/phosphate bond coat.
• An intermediate high temperature polymeric inhibitive coating.

• A PTFE impregnated topcoat that provides a barrier against corrosion and excellent resistance to fouling.

The coating system provides excellent protection to 403 and 410 stainless substrates when exposed to corrosive steam conditions or low pH wet chloride environments.

ADVANTAGES
The benefits of using SermaLon include:

• Smooth surface finish and PTFE impregnated topcoat contribute to performance recovery and reduced fouling rate.
• Superior resistance to acid rain, deicing fluids, decontamination fluids, hydraulic fluids, lube oils, and jet fuels.
• Excellent bond strength.
• Continuous protection against relative humidity to 100
  percent, and with continuous salt/mist in air.
• Excellent coating ductility.
• No hydrogen embrittlement problems.
• High resistance to corrosion fatigue.
  

APPLICATIONS
SermaLon is designed to be used on ferrous substrates such as:

• Centrifugal compressors exposed to wet chlorides or excessive fouling.
• Steam turbine components exposed to corrosive steam; e.g., nozzles, diaphragms, blades, wheels, packing areas, rotors and cases. (Note: Not intended to resist water droplet erosion.)
• IGV’s of industrial gas turbines.
• Various chemical process vessels.
