Good short VID on the issue. One thing that also impacts is the finish. Many people finish with oils and the majority of these are already yellow in some form. Finishing in a good clear car lacquer helps in two ways, one it is a perfectly clear hard wearing finish, but it also provides additional UV protection. Nothing of course will stop the yellowing, but a good clear car lacquer can add up to another 10 years before the yellowing is noticeable on the majority of colours. A lot of people don't like the lacquer finishes due too the high gloss, but there are additives used that can give you anywhere between full gloss and flat, personally on tables I use a 30% sheen.

Sorry, I can't resist. Aliphatic compounds can be cyclic...like the cyclohexane you drew. Add three double bonds (essential elements for generation of free radicals) to that structure, obey Hückel's rule on aromaticity and there you have it, an aromatic compound. This chemistry is also the essence of the drying oils like walnut, tung, and linseed oil. The rest of the talk was spot on and very useful.

Great video! Question. You mentioned that there is an opportunity for yellowing to occur during the curing process if an inappropriate amount of heat is generated during the cure. If this overheating does happen, but the epoxy does NOT yellow due to this, does it also mean that this epoxy will be inherently more susceptible in the future for yellowing? Or will it just have the same potential for future yellowing as an epoxy pour that stayed within the recommended temperature/thickness range for that epoxy's specifications?

Our Amazing Clear Cast Plus epoxy will help delay yellowing but unfortunately, all epoxy will yellow eventually.

in the complete absence of atmospheric oxygen, free radicles can still progress via oxidation pathways by binding to the oxygen that was originally incorporated in the structure of one of the resin components, kinda like how pure potassium metal can rust/burn in a complete vaccume if placed on a piece of paper. Actually, despite a surface patina that may form in normal atmosphere, this mechanism for oxidation and yellowing should always be the dominate pathway unless the resins are super thin because epoxy does a good job of blocking atmospheric oxygen. thats why its used in some surface treatments to prevent metal corrosion like on modern automobiles. cars are made of bottom barrel carbon steel that rusts pretty quick when exposed. also this is really semantic and the chemist in me that is cringing from the carbons with only 3 bonds in ur "aromatic" diagram, but it should be understood that its not the cyclic structure of carbon rings that absorbs uv light. some of the most common alipathic cyano components are unsaturated cyclohexane derivatives (a ring structure but with 2 hydrogens on each carbon in the ring). Its actually the existence of the double bonds that can rearrange very quickly in unsaturated/benzyl/phenyl rings or even straight chains which are the component that absorbs most frequencies of light/uv. the cells in our eyes use a straight/non cyclic molecule called retanoin to absorb light and see colors after all... the existance of simmilar energy rearrangments of these double bonds means that quatnum mechanically the bonds are actually some average of these states which spreads out the posistion desnity/probability density of the pi bonding electrons between conjugated (alternating double bonds) carbon atoms and therefore has overlap with the same energy frequency that makes up UV/visible light. because theyre simmilar in dimension and energy they interact and absorb the light energy which then produces the radicles. you can think of this like how only objects of a certian dimension in the microwave oven can actually absorb the microwave energy, and irronically two grapes are in that goldylocks zone of size and conductivity to where they actually act as a coupling antena and can ironically produce plasma/bust into flames in the microwave lol. most microwaves use wavelengths that are about 4-5 inches long. this has overlap with stealth fighter technology and methods of reducing radar cross section by making features 3x bigger or 1/3rd smaller than commonly used radar wavelengths to avoid electromagnetic coupling=radar return

Can you add yellow coloring and go with it? :)

So you're saying if I pour my resin in a sealed Helium rich environment instead of outside, it won't yellow as much?

How does UV resin cure without yellowing? I've noticed if I cure my projects on a white glazed surface it cures insanely fast and it's extremely hot. Like don't touch for a minute or you'll have a 1st degree burn hot. Lol So, my hypothesis is the heat. Also, is UV resin actually yellow proof? I heard this somewhere, and I was wondering if it's true.

Are you aware of the Retrobrighting used by people with old, cream colored plastic computer cases? Briefly, hydrogen peroxide+uv light can reverse yellowing of old plastic materials that have yellowed when exposed to UV light. I'd make a guess that the yellowing is caused by the same thing you're talking about. What's not well understood is the science of WHY the retrobrighting process works. There's also an idea that the yellowing of (often ABS) plastic is caused by the addition of Bromide to the plastic, which is often added as a fire retardant. Like most things on the internet, there's a lot of talk, but little experiment or results about if it really is bromide that's the culprit here. Would you have any insight into any of the above?

1:40 "You get a lot of Aliphatics in our clear and clear slow products. Those are our urethane resins." Not sure I understand. Even resins with a lot of Aliphatics will yellow eventually? thanks

Paint would block the uv but then what’s the point of using epoxy

Ok so are the uv stable epoxies BS? What about adding top coat that’s uv resistant 😱😱😱. Eventually will it still yellow. Thanks

UV resistant epoxies (like our Amazing Clear Cast Plus) help to slow down the yellowing process but they won't keep your projects from never yellowing - an epoxy formula can only handle so much UV resistance before it becomes too toxic or unusable.

@@AlumiliteCorporation I'm kind of curious how the yellow properties get distributed in the resin. Is it mostly the outer core the first to turn because that's where the UV rays enters from. If that's the case couldn't you just sand down old products to buffer out the UV damaged layer? What happens if you keep adding different layers of UV resistant resins? Will they yellow at different times? 🤔😂

@@meetyounever6923 i will venture to guess the seperate layers you are talking about would most likely yellow at conceivably the same rate unless you are waiting extended periods of time between layers. Applying the layers one after another within a few days or even weeks will most likely not make a difference in the long-term

So this is why its such a big buisnes. Customers see how nice it is when clear then you charge em to redo it when its yellow in a couple months
