Plastics and coatings are essential materials in industries ranging from automotive and electronics to construction and consumer goods. However, exposure to UV radiation, heat, and moisture can significantly accelerate material aging. Common signs of degradation include color fading, surface cracking, chalking, gloss loss, and coating delamination.
Accelerated UV testing enables manufacturers to predict long-term material performance within a fraction of the real-world time. The ASTM G154 standard provides guidelines for testing UV effects on plastics and coatings, ensuring that products meet quality and durability expectations.
Key Statistics:
UV-induced discoloration occurs up to 10× faster in accelerated conditions.
Coating adhesion may reduce by 15–25% after 500 hours of UV exposure.
Lack of standardized testing can result in premature material failures, leading to higher warranty costs and brand reputation damage.
The UV Accelerated Aging Chamber replicates sunlight, heat, and moisture under controlled conditions. It is critical for evaluating plastics, coatings, rubbers, and composite materials, offering accurate predictions of product longevity.
