Thanks Herman for the info, and as for carbon layups yes there are other resins that have been used with it such as vinylester. But if you check with a rep from one of the many companies you may find there are lots of other resins that may also work. Companies will also help with needed information all you have to do is call them. But yes I have to agree with Herman unless he is not measuring the epoxy properly. Or the layup is also very thick causing exotherm, but in a helmet not the norm. The aspect of water or humidity affecting the epoxy I have not yet experienced, as I work right on the water but will affect certain bagging materials such as pva bag. But in flexible molds products water and moisture does affect them.
