Answer 1

I don't think you'll find a paint that has this property.

You can look to the type of glass you're using, although this is not an easy fix. Filters or coatings are a better solution.

A filter is a potential fix. See below.

You can also get HR coatings for broad band IR. This may help, but depends on your application, these are applied to low emissivity windows (see physics today article)

Since you don't list your application, if you want more specific info, do a search w/ the keywords from above.
