Epoxy Warmer Box

13 Oct

Early last week was the timeline to sheath the inside of the centerboard case with 6 oz glass cloth.   The outside temperature dropped to the mid 50’s for a few days and since winter was approaching I decided to enclose my West System Epoxy inside of a warming cabinet.   I also purchased a couple of heat lamps to keep the area a bit warmer when the temperature drops below 60.    The center board case now has some timbers added, the first wood used that is not plywood.

    Thanks for your comments. We are getting some pretty chilly weather here also, so guess I will put a box together soon. The boat is outside under a canopy, next to the shop where I fab the components. It’s heated, but with all the coming and going it’s not much warmer than outside.
    I have not kept a blog, nor any kind of record except for material costs and a few pics. I’d be glad to share them with you if you’d like, and I’d be interested in hearing about your project.

    I’m building a Redwing 18 in my yard and need a warming box. Do you raise the temp just to normal working levels or compensate w/ the hardener?

      I have only followed recommended mixing levels. I try and keep both the epoxy/hardner and parts to be glued within the temperature range of the epoxy. I use the warming box to keep my epoxy/hardner around 60-70 degrees and use my warming lights on the areas to be epoxied for a while before use. I just now have been doing work in low 50’s and the warming lights and box are working well. The set up time is longer, but still is hardening out within the next day with the warming lights kept on the new areas of construction. Working time remains in the 10 to 15 minute time period so I still have to move efficiently. Let me know if your keeping a construction blog and I will link to it.

      If you are talking about epoxy and by “compensate” you mean adding more hardener….. That’s a big NO! You cannot deviate from the mix ratio with epoxy like you can with polyester. Read the instructions! That’s one of the nice things about polyester… the fact that there is a broad range of hardener amount you can use to get faster or slower cures.

    People that think Epoxy resins won’t hurt them because they don’t stink like polyester resins are doing themselves a great disservice. Proper respirators capable of protecting you from the vapors are essential unless you don’t mind frying your brain.

      Point well taken. I store my epoxy in this closed space box and always wear gloves, an N-95 mask, and work in a well ventilated location. I would use my space fan if working in a confined location. Here is the West Systems link to “How to prevent overexposure to epoxy” http://www.westsystem.com/ss/how-to-prevent-overexposure-to-epoxy/

    Who knew such things existed in the world. A solution to every problem.

    Amazing 🙂

    do you get silly at the end of the day from breathing epoxy?
