Weathering and light exposure are important causes of damage to coatings, plastics, inks and other organic materials. This damage includes loss of gloss, fading, yellowing, cracking, peeling, embrittlement, loss of tensile strength and delamination. For many manufacturers, it is crucial to formulate products that can withstand weathering and light exposure. Accelerated weathering and light stability testers are widely used for research and development, quality control and material certification. These testers provide fast and reproducible results.
