A resin that starts to cure during the infusion is killing the composite part you are making. So for infusing you need a very slow hardener. As I've said in a previous post, in my case gelling starts only after about 8 hours or a bit sooner when temperature is more than 20 degr.C

Do not compare these resins with hand-lay-up resins. Total different animal..
