Drying/Curing Box temp?

Ive made a plywood box with two bulbs(off to the side of the main unit) and a small fan to gently blow the warmed air into it. On the top I have put several vent holes which can be closed or opened to regulate the temp. What is the optimum temp I am looking for fastest final cure up. The rods will be going into the box once they are tack free.
Right now with all the vent holes opened (6) I can get it to a constant 110 F. I would like to get it warmer but dont want to hurt anything. Edited 1 time(s). Last edit at 11/16/2009 07:22AM by Scott Bazinet. Re: Drying/Curing Box temp?

You should be able to buy a thermostat that you can plug youre globes into that will regulate the temp automatically so you could be more precise with the temp. In Australia i bought mine from a homebrew supplies shop.

The best temperature for curing the epoxy is room temperature. ABout 70F to 75F.
For every 18F to 20F increase in temperature, you will halve the cure time from what it was at about 70F to 75F. ................. Re: Drying/Curing Box temp?

I understand this. If I am curing at 110 F will their be any long term negative affects or will I just simply get a faster final cure? Re: Drying/Curing Box temp?

i keep my box around 95 degrees and everyting works fine, it cures about as fast as it does during the summer Re: Drying/Curing Box temp?

There shouldn't be an problems with long term durability.

I run mine at about 90 degrees. I though have a little different thought about how I heat my enclosure. First I made mine all out of plexiglass so I had plenty of light coming into the box. You of course could put plexiglass windows in your box. Second, I personally don't want a stream of air blowing into my dryer box even If I filter the incoming air. I have a electrostatic filter on my furnace and I still have dust in my home from me and my two Parson jack Russells, so I don't want any of that blowing arround. So if you can't blow the air in, how do you keep an even distribution of heat? Well we are approaching the right time of the year to get the solution to that problem, Christmas. What I did was buy a couple strings of Christmas tree lights. You of course need the old Incandesant type that produce heat and not the new LED types. Since the Incandesant are slowly being phased out I would stock up on some replacement bulbs. Now you can stretch out these string of lights from end to end of your dryer box for even distribution of heat and no fans, therefore one less part to fail. Next I bought a house light dimmer switch and wired it to a conveinence outlet both installed in a double switch electrical box to control the lights and hence the temperature. I also bought light strings with a little larger bulbs (C9). I have a thermometer inside the enclosure so That I can adjust the temp to what I want it. Finally I turn the lights on in advance of using the dryer so I also keep my finish in there so it won't be quite so viscous when I use it.

Who has a good layout of a drying box, I am about to build one? Re: Drying/Curing Box temp?

Walt,
Basically, build yourself a plywood box with a plexiglass door on the front. Make it as long as needed and as large as necessary to enclose your dryer or dyrers that you want to use in the box. Essentially any thickness is fine to use as a box. Just make the material thick enough to give your box some stability. Another thing to do is to simply make a frame of either wood, or angled aluminum, and then use a thin material to sheet the angle aluminum. By using this method, you can cut the actual weight of the box by 2/3rds, if necessary. Take care Roger Sorry, only registered users may post in this forum.
