The cold season is coming and resin infusion become difficult if room is not heated. How do you do in this case?
Heating the resin in a water bath? I usually pre heat mold in oven, then I extract and start infusion. Artisanal way if I can’t heat room
your resin is thicker, but takes longer to gel. Is the permeability a problem? I usually have problems with warmer weather, and resin gelling too fast before the infusion is ready. Doing it in the evening is an easy fix for that problem 
I have the opposite problem in winter… with the cold, resin is not enough fluid, so infusion is a problem.
in summer you can refrigerate resin with ice :rolleyes2:
You need to heat the resin in the mould, not in the pot.
Depending on the mould size, you could use infrared heaters or warming blankets underneath.
I usually heat resin in the pot to 20/25°C because otherwise degassing is difficult. I heat mold in the oven to 50°C then I extract it and star infuse. I’m trying also to heat mold with a carbon fabric built-in the mold and crossed by current
I’m interessed in that kind of heating too. Did you get some good results yet?
this is a test, with a 30V transformer. Now I use a welding machine. Interesting but with attentions
The cheapest way to heat a mould is to buy a electric blanket, cut the heat wire out and laminate it in your mould, you can reach about 70°C, cost about 9€ /10$.
What kind of electric blanket? Can you post a link?
the problem with a heat wire is that fiberglass doesn’t conduct heat. I tried a mold with carbon fibre heat inside the mold, 3 cm laterally of carbon, the temperature was lower, about room temperature. When there was carbon heater at memory was about 40°C.
I think heat wire is not the way if the mold is not aluminum
All my molds are made in carbon fiber. So heat exchange is not a problem.
Create a box or room in your workplace, using foam sheets or similar, and heat that with a portable heater.
On top of that you could heat the mould, which can give great results. Instead of carbon, which is a bit conductive, you could use carbo-e-therm (future carbon) which works great.
But for good results at least get your working area to room temperature.
