Hello everyone,
I recently purchased a new Billy bookcase and noticed that the color of the newer models changes noticeably faster than with older ones. My question is: why does the color of newer Billy models change more quickly?
I observed that especially with the newer shelves, the surface often darkens or discolors unevenly after just a few months. This seems to be less pronounced in the previous model I bought several years ago.
From a technical perspective, what factors cause this? Is it due to the type of coating used, the wood material, the base substances, or perhaps the manufacturing process? I would appreciate detailed explanations, as I would like to understand this better.

PU coatings are generally more resistant to mechanical stress and UV radiation and retain color better.Exactly, that’s why PU coatings used to be the standard – now there is a growing shift towards more affordable alternatives.

That’s why manufacturers now use different solvents and binders, which might negatively affect color stability.This is an important point because stricter VOC regulations often lead to changes in paint formulations, which can impact durability.
