UV stable epoxy.

System Three offers one epoxy system called SB-112 that is UV-resistant. This epoxy system is formulated to have maximum ultra-violet light resistance consistent with its other properties. However, no epoxy resin system is ultimately resistant to degradation by sunlight. We recommend that substrates built using SB-112 epoxy be protected from sunlight exposure when not in use to increase longevity. System Three products that will provide protection, in order of effectiveness, are:

1) Pigmented Pennant Topside Paint

2) Pennant Paint Clear gloss and clear satin

3) System Three's Marine Spar Varnish
