Trying to find the most durable way to use resin pour in king color core type signs to add color.
Seems that the manufacturers do not recommend it for long term. read below.
This message was from West Systems,
i did get a response from some others that
are similar.
has anyone used resin inlay in king color core or polytone long term and had good results.
Dick:
Epoxy typically does not hold up well with exposure to sunlight. It initially looses its gloss and the color can change fairly quickly and eventually it becomes yellow and chalky. You can protect it for exterior applications by applying a good varnish or one or two part clear polyurethane (this is the best of the three) over it. If you use high percentages of dry pigment or mineral base powders like stone dust the epoxy holds up much better. It looses its gloss with exposure to the sun but retains the base color because the pigment and stone particles cast shadows that protect the epoxy below. If you get a chance and if you are interested, give me a call next week and I can fill you in with more information on the topic.
