As far as epoxy
and UV degradation - my boat
building buddy says it's easily solved
by using/adding what they call "Florida additive" which is formulated specifically for the tropical sun exposure. I believe it is called V140. It does give a little bit of yellowish tint but in wood related applications this should not be a concern. And that yellowish tint is what protects the epoxy
from the UV.
V140 is an accelerator, used to accelerate the cure rate and enable using some epoxies down to 35 F.
There are additives that purportedly make epoxy UV resistant, but since they are not part of the molecular structure of the epoxy, the epoxy exposed to UV 'between' the additive continues to deteriorate.
Nobody uses uv stable epoxy? :: Builders' Forum
West still seems to be recommending overcoating with a UV resistant material as the best solution for UV protection.
I have some 'UV resistant' epoxy resin, from Resin Research
, and have not been able, so far, to get satisfactory results with clearcoating various species of wood. Since I haven't gotten past the application stage, I've no idea how well the resin will hold up under UV exposure.
If you have some information on an authentic epoxy resin suitable for UV exposure, I would certainly welcome it...
