UV light's affect on epoxy hulls

[petn7]

I just bought an unbuilt Thor hull and it's a little bit yellower than I thought. I understand the yellowing is from UV light? Has the hull's structural integrity been compromise in any way? I would assume so, but perhaps in a negligible amount?

Any thoughts would be appreciated.

The gelcoat may be discolored but the fiberglass layup should not be affected.

Has the gelcoat's structure been affected in any significant way besides the change in color?

First of all there is no Gel coat on my hulls. The yellowing is normal and does not hurt the hull at all.

You won't break an epoxy hull- tough as old boots.

I will second that my alpha hull is well over ten years old and is yellow like you say and the integrity of the epoxy structure is just as good as when it was new

Epoxies vary in colour anyway. Hulls moulded in West Systems epoxy tend to be yellow from the outset. I use Reactive resins epoxy which dries clear, despite the yellow colour of the hardener.
