Structural epoxy system R2940 / H9054 for Vacuum infusion and RTM with fast hardener
Each kilo includes 0.81 kg resin + 0.19 kg hardener
Two component epoxy system, specially designed for Resin Transfer Molding process, vacuum infusion, injection, etc. It may also be used in hand layup (for flat surface molds or molds with no vertical surfaces). It exhibits very high mechanical properties, especially interlaminar shear strength. This system has a very low viscosity, and low reactivity for manufacturing of large parts. It also exhibits excellent retention of the mechanical characteristics in a wet environment. Temperature resistance: Tg1 max = 100 oC

Reactivity of R2940 / H9054 system:
Pot life on 500 g mix at 20 oC: 2 h 30'
Exothermic temperature (oC) on 500 g mix at 20 oC: 215
Time to reach the exothermic peak on 500 g mix at 20 oC: 2 h 40'
Polymerisation of H9054 hardener:
Time to wait at 20 oC before post-curing*: 6 hours
Minimum post-cure cycle: 24 hours at 40 oC
Advised post-cure cycle: 8 hours at 60 oC
*has to be respected in case of thick laminate (> 3 mm,) so to limit the risk of exothermic reaction.
