I think it prevents the underlying dye or stain from UV penetration. It does this by converting UV radiation to lower wavelength radiation mostly infrared. This means more heat. This heat is transferred into the underlying finish and will effect it. This is why UV coated Glass windows have a film heat dissipater applied between the UV coating and the glass. So if your finish is sensitive to heat then UV coatings should be applied on top of a dissipating coat.; such as a similar varnish without the UV coating in it.
That’s my opinion. I could be wrong.
Maybe Fred knows.
