Weathering is a complex topic. In some circumstances, combined attack, for example by UV and ozone, is more serious than separate exposures to the same aggressors. Moisture level often plays an important role. In some polymer materials, thin, UV induced, cross-linked surface layers provide partial protection against further damage. In others, the UV creates "color centers" that enhance the effect of subsequent radiation. Absorbing "UV stabilizers" can afford some protection for plastics.In all cases, the collimated and carefully spectrally characterized output of our solar simulators helps you unravel the complex interplay. The round-the-clock availability of high intensity levels allows accelerated testing. You can subject a test sample to the equivalent of many years of solar UV in a matter of days.
