Resin Question

Just wondering if anyone has used this resin or could answer this question.

The Description says:

"During application workshop temperature should be 18 - 20 oC"

Now the problem i have is im in scotland and its winter, the temperature just now doesnt often get above 10oC.
Does anyone know what would happen if i was to cast in this? Would it just take longer to set?

Thanks in advance.
 
Predanator! What you need is a homemade oven! I'm in Shanghai CHina and its a 14c fall temperature and I use oven like below to fast cure my resin parts.
It a box with open lid top inside lined with aluminium foil then place a heating lamp above it to heat the silicone with the resin liquid inside. The size of the oven depends on what you need
to heat up. Larger heat lamps for larger things. Be careful when you do this do check it every 5-10 minutes cuz it gets very hot inside. Good luck and I recommend googgling "homemade foil oven" for beter instructions.

Awsome! Thanks ;) Sounds like a plan, Just need to find a heat lamp now.
Well to be fair i still need to finish my bio (not the terminator one) but it shouldnt take long, Then i can start on the casting, fun fun fun.


-edit-
Just thought id add if i didn't use a heat lamp what would happen? would it not cure? or would it just take longer?
I know that longer curing resins give better detail but if its the same thing.
 
yep it would take longer to cure, as the catalist causes heat to make it set, As for the heat lamp thats defently a BAD idea if you play on re useing the mould as it drys the silicon out and reduces its " shelf life" which is naturaly done with the resin heat , but useing a heat lamp will reduce the number of pulls you get from the mould,

if they are just 1 offs then the idea is good
 
Here in michigan for winter temps, my uncle took a large box, put the stuff he just put a coat of resin on in the box, then aims a small space heater into the box. it keeps it at a constant temp and the resin sets perfectly. Him and I are 405th members, hes currently makin an MC helm.
 
Regarding the shelf life of silicone it depends on the type of sillicone used. I'm using a low viscosity-hi temperature Quality (expensive!) silicone thats good up to 200C+ so there's little worry from the tiny heat lamps that i'm using. My molds are usually about 1 inch thick all around so thickness will add durabililty. Thin molds will just die out. Plus the exposure to the heat lamps are less than 5 minutes cuz of the resin I'm using. So you need to estimate your curing time. With heat the resin parts are stronger and harder with less chemical instability - otherwise you jsut get a oily resin part that's half cured and toxic.
 
Thanks for the advice guys :)
I guess ill just experiment when the time comes. I have a small portable heater so ill test some form of heat box with that and see what happens. =)
