Hi there

The reason for the low temperature is as morepower suggests.  For surfacing pre-pregs we tend to go for longer to allow the mould to heat up rather than using set ramp up times as most moulds tend to warm up at a sensible pace naturally when placed in the oven.

For example for resin flow reasons you should always dwell the ramp up at 80C for an hour for best cosmetic results. You can then increase it to for example, 120C for 1 hour to cure if time is of the essence.

When using our Easy-Preg Surface Layer PrePreg Carbon with the Vari-preg we always increase the time, eg 10hours at 100C is a typical single temperature cure we might use.  You could ramp it up and dwell at 80C for a couple of hours then do a quicker high temperature cure, but in our experience allowing the resin to flow is key to a better cosmetic finish.
