Prepainted Miniatures, anyone know the sealer they use?

Recommended Posts

So I've been looking for a good sealer for a while and while I've found one I'm happy with the thought crossed my mind that prepainted miniatures (D&D, Mechwarrior, Mage Knight etc) have a rather amazing sealer. I've tried to scrape paint off of several in the past and have had no effect. Anyone know if it's just the sealer? Some combo of the paint they use that interacts with the plastic? Have any theories?

I may be mistaken but I don't think they use sealer, just some kind of paint that bonds chemically with the plastic. I have never seen anyone forthcoming with details of the type of paint used on these things, so I would guess it is a trade secret.

I was rather under the impression that the toy factories use a styrene and/or vinyl-based paint or plastic which is close to the same material as the toy itself and bonds with it.

 

They probably do not use acrylics, which are more expensive. They may not even use a sealer.

They use pigment mixed with a solvent. The solvent melts the plastic and the pigment penatrates the surface. So when it "drys" it has created a new colored surface. Its more like dyeing than painting.

That begs the question if there is some (safe?) additive we can mix with the Reaper paints to do the same with the bonesium?

Somehow I doubt it.

 

Any solvent strong enough to dissolve plastic is going to be pretty nasty. It also may well be incompatible with acrylic paint, which is itself a kind of plastic suspension.

 

However, I am not an expert on plastics or plastic paints.

Pingo beat me to the punch.  I agree that it's unlikely, especially since when people were opening their boxes after the first Bones Kickstarter there were concerns about off-gassing and allergic reactions just from the plastic.  Throw a solvent in and you'd likely get some very nasty fumes.

Krylon Fusion is an example of this.  It won't bond with all plastics but it is designed for some types of PVC.  However, I don't know about the bones material.  Plastics and solvents are almost a dark art.  I wouldn't mess with them unless you really know what you are doing.

And have a gas mask.

 

Maybe even a haz-mat suit.

 

Just to be safe. :blink:

I may be misremembering here, but wasn't it those very Krylon spray products that reacted so badly with Bones minis that they became sticky and never properly dried?

That sounds familiar to me too.

      I recently finished kaphrixis using the scale 75 copper metallics.  It's for a gift so it needs to be sealed and I am at a loss as to what to use.  Using either a glosscoat or a dullcote will change the brightness of the metal.  Does anyone  have suggestions on which way to go?  Or is there another option?  If it were to remain mine I would just put it in the display case unsealed.
       
      Thanks for any help.

      So I'm going to be repainting some D&D Minis for the DDM Guild's Prize support at GenCon 2018. Just really got started last night, but progress is progress. Sorry about the crappy phone picture.
       

       
      So, I'm gonna be keeping track of my progress here. My deadline is the first full weekend of July, the 8th or so. As I'll need to mail them to someone who is actually attending:(

      I’ve got some of both these products, but I’m not sure exactly how they’re supposed to be used.
       
      I’ve tried the primer a few times, but compared to spray primer it’s very liquidy (not a surprise, since it’s a liquid). The issue is I don’t know if it is being properly applied or just running off into the cracks. It doesn’t turn the metal white, but I don’t even know if that is supposed to happen or not. Am I using it correctly?
       
      As for the brush-on sealer, what is it for and what does it do? I’m assuming it goes on at the end, and if that means I don’t need to buy yet another aerosol product, that would be swell.

      I'm looking for a spray on sealant that won't make bones all sticky. I'm going to be applying some decals to my TARDIS and would like them to stay put. Any advice/recommendations?
