Need help on finding a substance

Need help on finding a substance

Need help on finding a substance

(OP)
I am a mechanical engineer working on a manufacturing project and need helps in chemistry.  I am trying to identify a substance that will reflect the invisible spectrum of light but not the visible spectrum.  The substance shall be in a thick liquid state in room temperature.  Could anyone help or point me to the right direction. Many thanks.

water

(OP)
Any idea finding a substance that will not dry up and appears dark?  Thank you very much.

RE: Need help on finding a substance

I think you may want to try the manufacturing and materials forums.
PS which invisible part of the spectrum: IR or UV?

RE: Need help on finding a substance

(OP)
Thank you for your tips; I will try the other board.  

It is the IR.

RE: Need help on finding a substance

Water will absorb IR and transmit UV light.

How much IR reflectance do you need?
Mirror-like or sufficient to detect the surface?

And for the non-reflected visible light:  Do you want that absorbed or transmitted, or doesn't it matter?

RE: Need help on finding a substance

please read my FAQ and give as much info as you vam.

Don't forget, there may an other way to skin your can....
