Epoxy system SR1710 / SD8824 (Fast)

Structural epoxy system SR1710 / SD8824 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

Mixing ratio by weight: 100 g / 23 g
Mixing ratio by volume: 100 ml / 28 ml

Reactivity of SR1710 / SD8824 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 SD8824 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.
