How does UV exposure affect the color of a rattan outdoor pet waste bin over time?

Over time, direct and prolonged UV exposure from sunlight significantly affects the color of a rattan outdoor pet waste bin. Rattan, a natural fiber, contains pigments and lignin that are highly sensitive to ultraviolet radiation. The UV rays break down these color-bearing components through a process called photodegradation. Initially, this may cause slight lightening, but continued exposure leads to pronounced fading, often turning vibrant brown or tan rattan into a pale, washed-out gray or yellowish hue. The intensity of color change depends on factors like geographic location, sun intensity, and whether the bin has any UV-protective coating. In some cases, uneven fading can occur, creating blotchy patches where certain areas receive more direct sunlight. This color alteration is not merely cosmetic; it signals the weakening of the rattan fibers, making them more brittle. To minimize UV damage, consider placing the bin in a shaded area or using a protective cover when not in use.
