Re: recone glueI cannot speak to any particular brand, but in general, slower curing epoxies "should" build higher molecular weight polymers and therefore have higher temperature resistance and stronger tensile strength from a chemistry standpoint, but with the exception of a short industry piece I sometimes use when teaching about polymers, I haven't look into it with too much detail lately.
