Polyester then anywhere from 1-5% by volume depending on how fast you want it to gel. Tom www.pandakayaks.co.uk

Group: Forum Members Posts: 26, Visits: 301	Ok, thanks. And what about the ratio epoxy resin-carbon fiber, related to the weight of CF? Is it 50-50? panda (10/05/2015) If it is epoxy, the exactly as it says on the bottle, any different and you will have problems with it curing and all epoxy resins can be slightly different depending on brand.

Some of the resin will go into the breather when you bag it so will bring it closer to the desired ratio. Tom www.pandakayaks.co.uk

Group: Forum Members Posts: 26, Visits: 301	Thanks a lot. I've started to use the vacuum bagging technique only a few weeks ago and only once I made the bag, not using the appropriate ratio CF-epoxy, but anyway having a good result. With the next bag I would like to have a better balance between the resin and the CF layers, just for this I asked.
