"Polyester resin is the cheapest resin available in the marine industry and offers the poorest adhesion, has the highest water absorption, highest shrinkage, and high VOC's. Polyester resin is only compatible with fiberglass fibers and is best suited to building things that are not weight sensitive. It is also not tough and fractures easily. Polyesters tend to end up with micro-cracks and are tough to re-bond and suffer from osmotic blistering when untreated by an epoxy resin barrier to water. This is really cheap stuff." http://www.redrockstore.com/resin.htm
Make a mold with it, don't fly it. -----Original Message----- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of Chris Johnston Sent: Tuesday, August 08, 2006 9:16 AM To: KRnet Subject: KR> polyester resin Can anyone tell me if polyester resin is safe to use on polyurethane foam, as far as I know it should be ok, and how well does polyester resin stick to wood spars, it seems polyester is very very cheap, about $12 dollars per gallon. I have been told there is a epoxy made by the araldite people LC 3600, whihc is supposed to be the bee's knees as far as soaking into the wood goes, has anyone any experience of using this product, its also quite expensive.
