What Influence the Yellowing Degree of Aromatic Polyurea?

04.Jul.2023 polyurea factory

We all know that the aromatic polyurea will turn yellow after exposure to the UV(why dose polyurea change color when used outdoors for a long time? ) ,but in fact, different formulation of aromatic polyurea change color in different degree, so as to the durability.


The above two pictures are three different formulations of aromatic polyurea, the three formulations added the same color paste, they are the same color before exposure, after 5 days of outdoor exposure, it can be clearly seen that the degree of discoloration of different formulations is not the same. In this regard, we will conduct long-term and in-depth research to provide high-quality solutions for customers with higher durability requirements.


Qingdao Polyswell is focusing on the research and development, production and sales of polyurea technology. We will always hold your back. If you have any questions about polyurea technology, please feel free to contact us.
