YOU'RE YELLOW! VF-25F turning all sorts of colors

Recommended Posts

Perhaps it's because I don't keep my toys in direct sunlight, but None of my White Valks are showing any signs of yellowing (knock on wood).

Seems I was mistaken. I took a closer look at my YF-25 again and it has very slightly yellowed. It's hardly noticeable unless I look for it. I am now fairly convinced that keeping my valks in their boxes causes them to yellow much faster, as I've had much older valks out on display that haven't yellowed at all.

Guess it's time to rearrange my display.

That’s bad news for me; I’m a closet collector lol

95% of my figs are MISB. I just don’t have anywhere to display them at the moment.

It's light and oxygen reacting with the plastic.  Just because you keep them in storage doesn't mean they won't yellow.  It has to do with how much bromine they are mixing and what they mixed with it, and how long it takes for the bromine to surface, how much light and oxygen it is exposed to, what the temperature of storage is (heat accelerates).  At least that's my understanding.  So I wouldn't take them out of the closet thinking that is going to make it better.  Maybe just open the box to circulate the air, in case it is chemicals that the plastic is giving off that are adding to the reaction. 

An example:

I bought a old G1 Jetfire off of ebay (not the one I restored above, but a different one.  You can tell that it was mainly in robot mode, because where the backpack was up, the area below the plastic was whiter than all the other parts, because it wasn't getting as much light.

In my case, the parts that are yellowing were consistent across all valks. Light wasn't the issue since they were in the box. For example, it always affects the nose and cockpit area, but not the bottom of the cockpit around the area where the landing bay doors are. On the bright side, the yellowing is mostly in the same degree so it doesn't look that terrible.

In contrast, all my valks on display haven't yellowed the slightest bit, despite some being a few years older than the ones that have yellowed.

Maybe more heat built up since they weren't in the open and/or the gasses that were being released couldn't dissipate and thus sped up the yellowing of the plastic.

In any case, I'll be keeping all my valks with predominantly white color schemes out on display for now.

We should be vacuum sealing the MISB boxes? Sealer bags that fit Arcadia sized boxes might be hard to come by and expensive :p

Expensive? Hmmm. Since vacuum sealing might help keep the MISB toy minty fresh why worry about expensive sealer bags? You want your toy to last forever, right? :rolleyes:

Doesn't everyone want to be buried with their valks so that future archeologists thousands of years from now can enjoy mint valkyrie toys?

My original Chogokin VF25 suffered the same fate, but the Renewal has survived the ravages of time. It is a nasty business given the cost of these things, but in a world of white Valks we're especially vulnerable ;_;

This happened to my 25F.  I'm going to disassemble it and try my modeling at what would essentially be a modern high complete model at that point.

Never mind the yellowing. My VF-25 Mikeal completely disintegrated before my eyes and I never transformed it and only displayed it in plane mode. It was forever in the cabinet and I wanted to transform it. Hence I do not purchase Valks anymore unless there is some special one and I would only buy used. I am assuming a lot of the 3rd Party Transformers and some Metal Builds will end up like this.

I have a part built Hasegawa VF1 kit, its been that way for at least 7 years the wings and body got painted but the nose section is only painted inside, its gone yellow.

all the unpainted plastic thats spent the last few years in the box is fine. So most definitely the uv got to it here.
