Why did my resin turn brown?
This yellowing is due to oxidation, a reaction with oxygen in the air which causes the amines in the hardener to discolor. As air exposure continues, this color will deepen over time, much in the way an apple or avocado will brown, once cut and exposed to air.

How do epoxies cure?
Epoxies cure by a chemical reaction between base and curing agent as already said. They do, however, need a defined temperature for that reaction to take place at. For DIY products usually 5-10C. If the reaction is stopped because temperature is too low it will start again when temperature rises although there are often side effects such as amine bloom you need to be aware of.#N#I've never tried putting mixed product in a fridge to stop reaction but from comments above maybe others have. Could be worth a try I guess but personally I would rather just mix the right amount in the first place!#N#Bear in mind epoxies will often exotherm as part of the curing process, expecially when left in a tin or mixing pot. If that happens it's probably to late to stop.

How long to mix epoxy resin?
Determine the gel time of the resin. For 100 g of epoxy resin (of a particular grade) i usually add 12 ml of TETAmine. I just mix it for 1 minute, not more than that. If the mix is getting heated up, viscosity will increase faster and will make working with the mix difficult.
What is epoxy made of?
The word epoxy comes from the chemical bond type called epoxide with a double bonded oxygen that opens to make new bonds leading to the polymerization of the epoxy resin. So, you have people loosely calling the finished, cured polymer - epoxy. Epoxy resin is the prepolymer or monomer that is a liquid made with epoxide rings in the molecules. This can then be cured when mixed with the exact amount of a curing agent loosely called hardener. Most people think epoxy polymer must start as 2 components that must be mixed to create the thermoseting polymer. In industry, there are formulations that ar
Why does epoxy heat up?
Epoxy heats up because it is starting to cure. You can slow it down by keeping the mixing on a flat surface, and keeping the temperature a bit lower in the room. Also, do not over mix the two parts !! A small bowl, in a very warm place, that is over mixed will cause a too fast a cure, and your mix will not flow well for the job.
Why epoxy over LED lights?
The more voltage applied, the hotter they get, and the shorter life they’ll have. Adding epoxy over them will cause them to retain more heat. More heat, shorter life. So first you should use the lowest voltage you can to achieve the effect you want.
Is epoxy toxic to breathe?
Are the cured epoxy coatings or castings toxic to breathe? NO.
Is epoxy bad for you?
Is it bad? It may be. You see, the process feeds on itself. When epoxy cures, it gets warm. When it gets warm, it cures faster. When it cures faster, it generates more heat and gets hotter. This makes it cure faster… and so on. This may end in an equilibrium, where all the heat generated is transferred to the environment and the temperature stabilizes. Or it may end in a thermal runaway. Then, if you are lucky, the resin will simply solidify in the cup before you can do anything useful with it. If not, it may melt the cup, burn your hands, or even start a fire.
How long does epoxy resin last?

How long does it take for epoxy to cure?
To layer different epoxy brands, pour the first layer and allow it to cure fully (usually 24-72hrs). Then sand the layer with a 80-220 grit sandpaper, clean off any dust and make sure it is dry. Now you can pour the second layer. Repeat this step any time you are layering separate brands.
How long to wait to pour epoxy?
Usually, when layering epoxy, I will pour, and wait anywhere from 2-12 hours, and then pour again before it is fully cured. This allows me to avoid doing the sanding and cleaning, which leaves room for errors and dust. Unfortunately, you never know exactly how the different epoxy brands will work when doing this. Due to unknown potential chemical reactions, it is best to wait until the epoxy is fully-hardened and go through the sanding and cleaning process. This minimizes any risk of ruining your epoxy in the process.

Can you run low on epoxy resin?

Can you mix different epoxy?
While at first when you look at epoxy, it may seem like no big deal to mix different epoxy brands – especially when considering they have the same mix ratio. While this is tempting for someone who jumps brands (whether that is a cost-based or intrigue-based decision), it is not advisable to do so. Mixing epoxy brands could cause more harm then good, particularly if they come from different manufacturers and have things added to them to increase volume – which is very common. If there is a way to confirm that these epoxies are private-label, and from the same manufacturer, it may be fine to mix them. The best thing to do in this case, before mixing for a pour, is to try mixing a very small amount to make sure it works as expected. If they are not from the manufacturer you really have four main options to use this epoxy:
