How does it behave against UV rays and outdoors?

We have accelerated aging tests that demonstrate that after prolonged exposure, the test specimens do not lose mechanical properties.

Although the pigment degrades superficially — meaning it becomes dull, like some paints — this is associated with the durability of the pigments, and the tested specimen maintains its initial mechanical properties.

But this is not only corroborated by the tests; for example, 1-inch diameter rods used to operate switches on electricity towers in the city of Los Angeles, removed from service after 40 years, maintained their mechanical properties intact. They actually acquired 5 to 7% more mechanical strength.

This is explained by the fact that the resin system (polyester, vinylester, etc.) continues to cross-link over time.

In the primary test, at machine output, the material is approximately 95% polymerized. And if we obtained that difference after 40 years, it means it did not lose any mechanical property.
