Hi 

 Has anyone had any problems with pigments in PU resin loosing colour and becoming patchy over time? I am using Xencast toughened P6 with EC pigments, no fillers, mech mixed, de-gassed the parts are nice colourful and shiny when they come out the mould, after a few days the colour is dying back but the parts are still nice and glossy.

 Any help would be appreciated.

Thanks

Sorry for the delay Warren this is how it tends to go, It's not as prominent in the pic but it can be seen, as I say they start off all jet black, 8% is the ratio I am using.

Cheers
