I would sort of hope that they have used an isophthalic polyester rather than an orthophthalic resin in a structural application like a seat, especially for that price. In any case, doesn't sound unreasonable to me. Edited 9 Years Ago by Hanaldo

As for links, Easy Composites stock them. Their IP2 infusion polyester is an isophthalic resin, and I believe their GP laminating polyester is an orthophthalic. Both are UV stable.

Not sure what you want me to say, but polyester resin is UV stable without clear coating it, and I had a quick look at the Tillett seats and they look like good products. I can't say I understand where you are coming from.

Polyester is UV stable, it should not yellow in the sun. However if you are using UV sensitive materials in the laminate (like Kevlar), then you would still need to clear coat with a coating that actually absorbs the UV radiation. Polyester may be UV stable itself, but unless it has a special additive in it then the radiation will still pass through to the laminate. This won't affect materials like carbon, but Kevlar will certainly degrade when exposed to UV.
