Enamel paints to allow heat exchange?

[amrmohammed]

Hey,

What type of enamel paints is suitable to paint the tube bundle in heat exchange so that it allows heat transfer (minimize heat loss in the paint)? heat conductivity is not usually mentioned in paints specifications.

Thank you ..

Conductivity is usually of inverse linear dimensions. A few micrometers shouldn't reduce heat transfer much.
