I'm pretty sure this ridiculously obtuse first post, made on a 10 year old forum, is courtesy of a spam bot.
But if anyone happens to be freaking out about csm and epoxy
, csm is held together for ease in handing and cutting by a styrene soluble binder. This binder dissolves with polyester resins which typically contain styrene and so the wet out and shape conforming gets a lot easier. I recall
reading on a few glass suppliers sites (mertons etc) that as long as you take the extra time with epoxy
to get a thorough wet-out, you wont have any problem. Optionally you can put a splash of styrene in your epoxy brew.
