Hello everyone, I have BILLY shelves from IKEA and I have noticed that the color of the furniture changes over time, especially when exposed to direct sunlight. I am curious: why do the colors of BILLY furniture change? Are there specific factors such as the materials used, coatings, or environmental influences responsible for this? Is this a form of material aging or rather a characteristic of the manufacturing process? I would appreciate an explanation that covers the typical building materials and finishes used in BILLY furniture and perhaps also how to at least reduce the discoloration.
Regarding chemical aging: Chipboard furniture like BILLY is coated with melamine resin or laminate films, which primarily protect against moisture and mechanical damage. While the melamine coating is durable, it is not UV-stable because the pigments and resins it contains are photochemically broken down when exposed to UV radiation over time.
These degradation processes cause color changes, usually fading or yellowing, depending on the pigmentation of the surface. Different colors contain different pigments, so the color durability varies accordingly.
Manufacturers such as IKEA do not provide exact UV protection values, but it is clear that furniture designed for indoor use is not intended for direct sunlight exposure.
Additionally, moisture absorption by the chipboard can cause slight swelling and shrinking, which may lead to minor surface distortions and thus intensify color variations.
Therefore, color changes are a combination of UV-induced pigment breakdown and material-related factors.

Can you be more specific about how laminate or foil surfaces react to UV? UV rays break down chemical bonds in pigments, causing the surface to lose its color.

Are there any reliable tests or manufacturer data on this? Manufacturer information is often vague. However, tests show that melamine surfaces used in furniture do not provide strong UV protection, so colors fade over several years.
In summary, the color of BILLY furniture mainly changes due to UV exposure, the quality of the coating, and environmental factors such as temperature and humidity. To avoid this, it is advisable to keep the furniture out of direct sunlight and maintain it properly. Furniture with specially UV-resistant surfaces offers more protection, but this is not available for BILLY.
