Does anybody have actual scientific test data about how many coats of paint are needed to protect composite aircraft from UV damage?

I was thinking UV is more energetic than visible light, so just thinking about opaque coverage for visible light might be irrelevant. UV is between X-rays and visible light for example. On the other hand a thin clear coat of sunblock rubbed on my skin protects from UV. Can anyone explain this?

I want to know the minimum thickness of white paint to protect epoxy from UV damage without using any primer.
