We usually find some beautiful items become dim,like the surface of electrical wire,the car lools not vivid as before,partly because of the exposure by ultraviolet light.It is natural phenomenon in our life.
With regard to PU products,some light colors,for instance,white color,light grey color,pink color,light blue color,complexion color and purple,they are more easy to yellowing and hydro-degradation.
Therefore,how to guarantee that happened?
Generally,we spray UV absorber to delay the yellowing and hydro-degradation.We suggest that to ask your supplier to pay more attention to these colors and advice your client these kind of colors are easy to yellowing and hydro-degradation.Or else,client may complaint if you don’t share the news to them.
