UV Reflective paint

Q. I am building a light box which will have six UV CFL bulbs outputting at 311NM.

I want to paint the inside of the box.

I need a paint solution that diffusively reflects down to about 300 NM.

Its for home use, so I need to keep the costs down and non-toxic.

Any ideas out there? Thanks!

A. Hi Steve. If you can build the light box out of aluminum, I think you'll find that it meets all of your needs well. A quick sanding will probably make it diffuse enough.

Thanks Ted,

I am limited to a wood frame.

I did some research and apparently PTFE sheets are diffuse reflectors.

I found a place on line called eplastics.com that sells sheets in various thicknesses.

So far that looks like my best bet.
