Has anyone ever tried putting Easy Cast resin in the oven on “warm” to speed up the curing process? I thought I read somewhere a long time ago that you could do this as long as it wasnt too long and as long as the temp isnt too hot. Im trying it tonight, I can let you know how it goes. Just wondering if anyone has tried this??

Karen, I have never tried putting resin in an oven. I used to have a dedicated toaster oven in my jewelry studio for miscellaneous projects, but since it finally quit working, I just havent replaced it. I would certainly say that I wouldnt do resin in an oven that you also wanted to cook food in.
One little experiment that I have done though is to take a heat gun to the Easy Cast resin and found that when I blasted it with heat, it completely cured in two minutes. The problem was that the resin cured a bit cloudy, party because of bubbles, partly because it now had this white-ish haze.
I would love to know how your experiment turned out!

Thanks, Katharine, for your post!
I recently purchased a toaster oven for use with my polymer clay projects, so I tried it out. I used it on the lowest setting (150 degrees F) and kept it in there for about a half hour. Then I let it cool for a bit, went back to it a little later, and compared the one that was in the oven to the one that was not. What a huge difference! The pieces that were in the oven were completely cured and hard to the touch (no fingerprints)! Keep in mind that this all happened within a 4(ish)-hour time span. Thats a pretty huge difference! I would like to try it again today if I have the chance to work on my resin pieces. I need to put a back coating on several pendants but Im not sure how it will work the 2nd time around. I dont want the front (bottom) layer to melt and have the backing layer fall forward (if that makes sense). So I need to think through that a little more. But the first time around, having it cure quickly was a success!

Ugh. So today I used a deep flex mold in the toaster oven and it melted. I set it on the "warm" setting at 150 degrees F instead of the bake setting. So needless to say, I am very frustrated and confused right now, as when I did it before it worked out really well. Just wanted to give a warning to watch the molds as apparently there arent all heat resistant like I read.

I actually sometimes to it in my food dehydrator.
Warm air basically. However it will produce more bubbles.
Maybe vacuuming it first will solve that.

can i put epoxy resin in uv lamp?
November 3, 2014 at 7:14 am #1617Katherine SwiftGuest
@Tamara, the UV lamp wont help epoxy resin since epoxy needs heat to cure.

You need a vacuum drying oven in which you can add an inert gas to get perfect results. Silicone and resin material will harden faster under heat because it is a chemical reaction. You should consult the manufacturer of the material.

I place my resin molds on a heat pad for curing, high for an hour, low over night. Seems to help with bubbles and cure faster. However, I prefer to wait the full curing time before working on them.

I recently purchased your opaque resin pigments – I love them – the colours are so vibrant… But I must say, even though I pay particular attention to the ratio of my resin to hardener as you advised given the pigment amount used counts towards to the total of part A, my resin is not curing to the desired hard finish.
I have tried two things:
I have given it another day to cure at room temperature and it is still bendy/mushy
I have put it in the oven on low (130c degrees)for a while and unfortunately it did harden and fully cure but it also changed the finished colour dramatically! So while I start out with the perfect coloured resin to get it to cure fully I need to bake it but that ruins the colour 🙁
I use a quality epoxy resin with a mix ration of 100:50 purchased in Australia from a store that specialises in resin casting/mold making/special effects etc…
Can you offer any advice to me so that I can get fully cured resin pieces that retain their vibrant colour?
I can send you some photos next time I pour some resin if it helps!
Much appreciated, Lauren 🙂

I so glad to hear you like the Resin Obsession colors! As for getting the resin to cure harder, here are a few thoughts:
1. The Resin Obsession color pigments were designed for use specifically with the Resin Obsession super clear resin. While I have had success using them experimentally in other epoxy resins, I can’t guarantee they will work with every brand of epoxy resin.
2. Since the color contains extra epoxy, you may need to add extra hardener above what the other manufacturer recommends. In general, extra heat and time won’t cure resin that didn’t have enough hardener to start the reaction.
3. 130 degrees Celsius is much hotter than what I recommend for curing resin. I like to use an oven set at 150 degrees Fahrenheit (65 Celsius) for 1 hour when curing the Resin Obsession super clear resin. I haven’t used oven curing for super clear resin colored with the Resin Obsession pigments, so I don’t know if that temperature will effect the final cured color or not. (That temperature really isn’t that hot, so I would hope not.)
Let me know what you try and if it works.

Just tried the heat gun method on my Almost completely cured resin. It worked. I put it on low for a few moments then switched to high for about 4 minutes. Let it cool for a moment before checking it and it wasn’t tacky anymore. Usually I use the 110F AZ heat. But it’s getting cooler now and the sun is setting earlier.

I will reply with my experience of using a toaster oven to help cure polyester resin. I normally start with a pressure pot for 2 hours to reduce bubbles. after removing it from the pot they are still very tacky. I then place them in my toaster oven for 1 to 2 hours at a temp of 110 degrees. Once cooled they are cured and clear and ready to turn on my lathe. (I do pen tunings)

I used the cool air and low settings on my hairdryer to speed up the curing on some custom pendants. Worked like a charm. No white haze unlike the toaster on warm route I’ve taken before.

Hi! I have a question about when to apply your resin gloss sealer spray:
I applied 3 coats of polyurethane resin to the top of a leather headdress base to make it strong enough to carry weight. It has been several days, and it has hardened up, but the polyurethane still smells horrible! And I read that it can continue to off-gas for up to a month while it cures! I see on your site that your resin gloss sealer spray can be applied over the top of polyurethane resin to seal in the smell (or help it cure?), but how long should I let the polyurethane resin cure before applying the resin gloss sealer spray?

Once the resin has fully cured (whatever the manufacturer says), you can apply the gloss spray.

I mixed a little one-hour-dry-time epoxy resin on a small piece of wood. After I used it for a task. I wondered if I could speed up the drying so I put the unused remainder of the resin on the board in the microwave for 15 seconds. It had turned white and foamy and had more or less liquified. I scraped it up into a blob on a stick, and 15 minutes later, it had resumed the sticky firm texture perhaps just a little bit more cured than before.

I’m new to resin art, but have had good success curing resin in my food dehydrator on the lowest setting. Pieces are hard in a number of hours. A great time saver if you are layering resin.

Hello, Have you come across or know of a catalyst for RTV acetic cure silicone?
I purchased some on ebay a few years ago, seller is no longer selling it, seller had stated that the chemist has moved elsewhere & was none left at hand, no further comms there.
The catalyst sped up the curing time to around 15 minutes, cost around $5 at the time, came packaged in plastic bottle (approx. 88mm x 40mm). Powder was red in color. One had to add water upto the marked level on the bottle shake and add to the silicone. 2-5 drops of the catalyst per 10grams or 1 squeeze of the silicone dispensing gun.
No clues as to what it was, have looked at the messy put the silicone in water & knead it, have seen the corn starch method, but the amount of corn starch in those methods is huge by comparison.
And info would be welcome.

I am a bartender at a restaurant that has a mug club. Our mugs are custom ordered with different logos/names/nicknames on them. The mugs are glass. I took it upon myself to secretly take some of our regular customers mugs to a huge Chicago Bears autograph signing. Autographed with sharpies (the gold sharpie was the best) and then my newbie self painted them with clear gloss epoxy. I did some research because I was worried the epoxy would make the signatures run. Opened my oven door, set temp on the lowest, °170, turned on my kitchen fan, sat the mugs on a no stick pan on the opened oven door. Rotated the mugs several times over 2 hours. Let them cool. Boom. Perfect. The product I used was Amazing Clear Cast. Hope this is helpful for someone. I have pics if interested

Has anyone worked worked with the resin Brand Art N Glow. I have recently purchased that Casting & Coating Epoxy Resin by that brand. I also purchased a Nail UV light but for some reason it didn’t cure it right away. Am I doing something wrong?
August 16, 2019 at 6:30 pm #80557
I don’t think Art N Glow is an UV resin. A light won’t help to speed up curing.
