Zinc Pest, "Resin Rot", valued models that crumble when touched! (1 Viewer)

[cks1]

Hello all.

Has anyone experienced any issue with “Resin Rot”?

I collect diecast aircraft, tanks etc and several valued models have suffered from Zinc Pest, this is generally caused by poor materials primarily with the zinc alloy used to cast these models. Over time your prized models just discintergrate, litterally crumble in your hands.

Is there a similar issue with resin-based models, “Resin Rot”?

Yes, there can be. Just as lead rot and zinc rot have to do with the composition of the alloy used to cast a metal figure, it is possible for the resin batch used to cast a particular object to be off, and to result in a cured resin that is of inferior quality. I have not seen it myself, with any of the resin kits I have built. But I have followed discussions on the painters' forums, such as PlanetFigure or Timelines, in which others have talked about getting a resin figure that showed signs of a bad batch. For example, the resin had an odd texture, or was softer than other figures from the same manufacturer or compared to other manufacturers' figures. Or it crumbled when worked. Or it had an unusual smell, not like the usual good casting. In the case of kits from legitimate makers, they replace the defective pieces on request. But many people have also pointed to pirate copies as often being cast with poorer quality resin, and that is another argument not to buy a figure that is obviously a pirated copy.

In the case of our branch of the hobby, I'd say that if you suspect that there is a problem with an object cast in resin, contact the maker, or the vendor who sold it to you, as your first step.

Prost!

Thanks Baron for that very informative answer..

Can resin go “off” and rot after a period of time, the Zinc Pest in some diecast generally takes a number of years before it shows?

I don't know if it helps, but I soak zinc and lead items in water and vinegar, then use a bristle brush with my Dremel before repainting.
