Poly-fiber System™,
Owned by Consolidated
Aircraft Coating.
The Poly-fiber™
system is the only vinyl based system on the market. They have
their own fabric and it must be used for their STC to be valid. The
fabric is attached with their Poly-Tak™
adhesive and heat shrunk to 350 degrees. Attachment to the ribs is
by the normal methods.
The fabric is sealed with and the finishing tapes are applied with
Poly-Brush™.
The first coat of Poly-Brush™
is applied with a brush and is put on before rib attachment. After
the finishing tapes are applied, a second coat of Poly-Brush™
is applied either by brushing or spraying. UV protection and fill is
provided by Poly-Spray™,
which is their silver. There is a choice of top coat between Poly
Tone™,
Aero-thane™
or Ranthane™.
Poly-Tone™
gives a dope like semi-gloss or satin finish. Aero-Thane™
and Ranthane™
are both Polyurethane wet look type of finishes. If Poly-Tone™
is used it can be rejuvenated in later years as the finish starts to
dry out. Unlike dope, Poly-Tone™
may be used on properly prepared metal or fiberglass. If either
Aero-Thane™
or Ranthane™
is used, rejuvenation is not possible.
To
repair the Poly-Fiber™
system, regardless of the finish, you have to remove all the
material down to the bare fabric. Once it is all cleaned off, glue
on a patch and build the finish back up again.
The Poly-Fiber™
System will not support combustion when it is completed. However,
it is flammable during application. Poly-Fiber™
has one of the best manuals that is available for covering aircraft
and using their covering system.
As a safety note, when spraying the Poly-Spray™
or Poly Tone™
you should wear a respirator at all times. When spraying the
Aero-Thane™
or Ranthane™
a fresh air breathing system is required.
