Epoxy with pigment

[Tradewinds]

I know standard clear epoxy resin doesn't like UV and tends to go brown.

What happens if it's pigmented? For instance, if I was to use a compatible white pigment would it go yellowish over time? Same with a light grey or similar.

Not life or death, but I would be interested to hear from those in the know.

I would be reluctant to use pigment if the work was structural. I have though used some pigment in epoxy when filling to give some more depth to the paint colour.

I have pigmented epoxy filler cream and black to create stripes in teak veneered flooring. Not exposed them enough to tell whether it reduces UV effects.

I glassed a rudder with epoxy and covered the rudder in white pigmented sp epoxy , after two years it had gone cream on the surface so I covered it in good primer and two pack white paint, that last until I sold the boat two years ago.

Nothing structural, just cosmetic.

Thanks for the other answers.

I know you can use West epoxy pigmented with graphite (or some such) to create a faux black caulk effect for decking - but it's white & very light pigments I'm curious about.

I've used an epoxy putty product in the cockpit called Marine-Tex in my cockpit which has stayed white & not degraded in over 15 years - but that doesn't seem to be available in the UK.

Wonder if oldsaltoz is around to comment?

It degrades and yellows, in particular, epoxy paints "dust" as the epoxy degrades and releases the filler or pigment, two pack poly for surfaces exposed to UV.
