Hi gents,

As the title suggests, is there a way to speed up the curing when skinning parts? I hate waiting 8+ hrs for the part to be fully cured before I can start sanding. Would baking it do anything?

Regards,
Stan

Hi Stan The Man
No need to reach a high temperature to speed up the curing, anywhere between 25-30 degrees will work,you can use a cheap fan heater directed at the parts and if its a small enough item place it in a cardboard box with one side open and direct the blower into one open side of the box.

Will it make any difference if I put it in the oven and turn the fan on? Or that doesn't work with skinning. The part is really small so it can easily fit in my oven. If so, what temperature should I set the oven at. The ambient temperature around here is 30 degrees and it takes about 6hrs for the part to fully cure. If possible, I really want to go under that time hence my question about the oven

Hi Stan.

I am about to try out a new technique on my next project to speed up curing times for vacuum bagging and I intend to use a heated blanket ( the type you would put on your bed). This should allow me to maintain a fixed temperature all around the table/component. At £19.99 from Argos it is a cheap way to do this.

If this is a suitable way to do this then I would think that building a basic frame around your component to stop the blanket touching it and then wrapping the heated blanket around the frame could give a much more even distribution of heat to speed up curing process ?

you could put it in your oven, I mostly put my oven at around 50°C, should reduce the curing by half... if you go 10°C more it will again reduce some hours
but keep in mind that the resin will be more fluid due to the heat... so a bit of resin will start to drip of the part, but that shouldn't be a problem!

Use Resin Research Kwik Kick. Its cures almost as fast as polyester.

I put it in the oven at 50 degrees and it worked like a charm. After an hour, the resin was rock solid. Thanks gents
