ASTUV is an industry-first technology that combines UV-curable coatings with UV irradiation in the anti-fog coating process for automotive lamps. By eliminating conventional hot air drying, ASTUV significantly reduces energy consumption while improving product quality, including preventing water drip marks inside lamp lenses.
As the automotive industry accelerates efforts to reduce CO₂ emissions across manufacturing processes, Stanley Electric continues to promote energy-efficient production technologies. Through innovations such as ASTUV, the company aims to support carbon neutrality while meeting customer quality requirements.
