Question

Can we use poluyuethane Aerosol materail in the making of aircraft engine parts?

AS WE KNOW THAT POLYURETHANE AEROSOL IS THE LIGHTEST MATERIAL KNOWN TO MAN CAN WE USE IN THE DESIGNING OF AIRCRAFT PARTS?

Answer 1

Since you ask the question, I assume that you are building a plane under the Experimental rule. I don't know in which country you live nor the specific experimental rules for that country but ... do you build an engine? I assume then that you mean to install a modified car engine like a VW Limbach, or a Rotax or Jabiru engine on an experimental aircraft and you need to paint some parts.

My homebuilt Kitfox aircraft is beautifully Polyurethane painted. That is: the fabric of the fuselage and wings. I guess you will be able to paint some parts of the engine like an airbox, with Polyurethane. But anything else that gets hot (as engines usually do) cannot be painted with Polyurethane. You will find in many car parts shops aerosol paint that can withstand temperature up to 600 degrees Celsius but even so, I tried that once on my Rotax engine and I got a bad smell in the cockpit.  ... Good luck with your project.
