In case of an aircraft fire, keep your
temperatures low until you can safely land!
Aircraft Extras, Inc. has negotiated with
Contego to offer the homebuilder, Contego Fire Protection for Experimental
Aircraft in quart and gallon sizes!
Contego - is a
heavy-bodied, Passive Fire Barrier, single-part latex designed for use on
various construction materials such as Wood, Aluminum, ,Steel, Stainless Steel, and many other
materials. It has been proven very effective in homes for preventing the
spread of fire, and now it is being used for aircraft.
AREAS of PROTECTION
Under the instrument panel
or anywhere fire may break out
When activated by heat or
flame, a dense carbon char is formed separating and shielding the substrate from
heat while off gassing displaces oxygen from the treated surface; thus
eliminating two of the three components needed for combustion.
HOW TO USE
Simply prepare the surface of the firewall or
etc. just like you would before you paint anything. Clean the surface.
If the surface is smooth, etch it so paint will adhere to it. Spray the
Contego on. Paint until you get approximately a 21mil thickness (0.021
inch). Let dry.

panel was completely destroyed in under 18 minutes with gradual
temperature increase as noted in graph.
Treated panel had heat applied as noted in graph under identical setup as
untreated panel. Test was conducted for 2 hrs and 15 minutes at which point it
was discontinued. The panel temperature never reached 400 ° F as noted in
It can be tinted by the end
user up to 10%, which gives a pastel color at most (the product has a lot of
TiO2 in it) - more relevant, it can be top coated with whatever you like.
paints can you use over Contego?
If so, does this compromise
the fire barrier? Use anything without compromise - an acrylic latex is
technically the best. The only no-no is alphetic polyureas, but it's highly
unlikely that anyone will try that.
3.) Does painting over
Contego compromise the fire barrier?
Use anything without
compromise - an acrylic latex is technically the best.
4.) Do you
recommend painting Contego on both sides of the firewall?
You only apply Contego facing
the area where there is a risk of fire. You apply Contego to the engine side of
the firewall. An engine fire burning toward the cockpit is a large risk to
the occupants of the cockpit.
