What is a common characteristic of coatings with high pigment concentrations?

Coatings with high pigment concentrations typically exhibit better UV resistance. This is largely due to the fact that pigments can provide a protective barrier against ultraviolet light, which is known to degrade certain substrates and coatings over time. When a coating is rich in pigments, it often results in a thicker layer that can effectively absorb or reflect UV rays, thus enhancing the durability and longevity of the coating.

Higher pigment concentrations also contribute to greater opacity; they don't lead to transparency, and can influence drying times depending on the type and formulation of the coating. In general, while some other properties may vary, the ability of high pigment coatings to resist UV degradation stands out as a significant benefit in protecting surfaces from the harmful effects of sunlight.
