SermeTel 5380 DP Coating System
SermeTel Process 5380 DP™ Coating System
®
SermeTel® Process 5380 DP™
(Dense Pack) consists of a closely
packed aluminum-filled chromate/
phosphate basecoat, sealed with
a chemically inert chromate
phosphate topcoat. The coating
provides excellent protection to
stainless steel and ferrous alloys,
and will operate at temperatures up
to 1200°F (650°C).
Advantages
millions of hours of successful
service in military and commercial
aviation and industrial turbines.
Specifications
Flight Turbine:
Pratt Whitney Aircraft
PWA 110-21/-9
Pratt Whitney Canada CPW 420
Ground Turbine:
Westinghouse 83342NU Dresser Rand 015-009-022
Solar ES59-263 Type B, Type C
European Gas Turbines 525202
SermeTel Process 5380 DP should
be used on any component where
serious concerns are corrosion and
erosion protection, tight tolerances,
and surface finish, or where the
potential for media entrapment is
possible due to part configuration.
On dimensionally critical surfaces,
precision coating thicknesses as
thin as 0.3 mils (7.5µm) can be
achieved.
Physical Properties
Other advantages include:
Thickness
0.3 to 5.0 mils (7.5 to 127 µm),
typically 1.5 mils (37.5 µm)
Surface Profile
≤ 10 µinches @ .010" cutoff on new
flight components (.25 µm @ 0.3 mm)
• Does not require media
finishing to achieve final
surface finish
•Compressibility supports
mating surfaces
•Excellent corrosion resistance
•Excellent surface finish
Applications
The aerodynamic finish of SermeTel
Process 5380 DP makes it ideal for
any gas path turbine component,
such as compressor blades,
vanes and shroud assemblies,
and diffusers. Similar SermeTel
