    I just gutted an old fridge to store Epoxy and other Resins in, away from the cold.

    I have heard of some people putting low wattage light bulbs in to warm things up a bit, but I wondered what the risk of Vynelester fumes catching fire from say hot bits of the lightbulb or even sparks might be.

    Any one have any thoughts about it ?

    I think he means just for storage.

    Couple of things:

    For a fire / explosion you need the following:

    oxigen (plenty around)
    fumes (moderate to plenty around, needs to be between lower and upper explosion limit)
    ignition (sparks from the bulb, or a surface hot enough)

    With 1 or 2 low wattage light bulbs (say 30-40 watt) I GUESS you will not reach any limit, and your resins are nice and warm.

    With an electric blanket you never get a very hot area, and they have a thermostat.

    Thanks guys - the electric blanket gives me the warmest feeling ... but of course they are bigger than fridge and should never be used folded.

    I need an electric bum-warmer .....

    They make small heating pads too. I have one that is about 25cm by 40cm

    Whoa your both talking wrong ends, one of you is talking about storing epoxy and one is talking about accelerating going off time in cold weather.

    There are thermostats for home heating control of base board electric heaters that would do the switching fine, but I am not sure about how they would live in that environment. Around $ 25-- US dollars for the low tech ones.

    I dont think anyone was mentioning catalyst going off in cold weather till now, but I wasnt aware it was ever a problem. I had always thought it was like Acetone, as long as it didnt evaporate, it was OK, and that heat made it deteriorate over time.

    Its relatively cheap, so I was nt too concerned about it.

    Also, I understand that you dont want to keep the catalyst and resins in the same container.

    All suggestions welcome
