accelerated weathering

Accelerated weathering is a laboratory process that simulates the effects of natural environmental conditions—such as sunlight, rain, and temperature changes—on materials like plastics or coatings. By exposing samples to controlled, intense conditions, it speeds up aging and degradation, allowing researchers to evaluate how materials will perform and last over time in real-world environments. This helps identify potential durability issues without waiting for years of outdoor testing, ensuring products are reliable and withstand environmental stresses.
