Post Curing IN2 Infusion Resin parts

Hi Matt,

The data sheet for your IN2-Infusion Resin gives the following schedule of times@temperatures for post curing:

24hrs @ room temperature
6hrs @ 40C
6hrs @ 50C
12hrs @ 60C

The Maximum Tg (glass transition?) temperature for the IN2 Infusion Resin is given as 94C - 100C for the slow cure mix. Is this the maximum temperature that this resin can be post cured to or should it be post cured to a lower temp? Ideally I would like to post cure to as high a temperature as possible as the parts are structural and will be subject to intense solar heating at times.

Can you suggest a post curing time@temp schedule beyond the one given above (say to 80 - 100C)? I understand the temperature ramp-up rate can be critical to the finished part's strength.

I am using both 5mm and 10mm thick closed cell PVC foam core material in my laminates - what temperature can this foam board take before it starts to degrade - can it withstand the higher post curing temperatures?

Thanks,

Phil.
