Scope of Application

【Operating Instructions】

Used for artificial aging tests of various materials such as textiles, dyes, leather, plastics, paints, coatings, automotive interior parts, geotextiles, electrical and electronic products, and colored building materials under simulated sunlight exposure. It can also perform color fastness to light and weathering tests. By setting conditions such as irradiance, temperature, humidity, and rainfall in the test chamber, it provides a simulated natural environment for testing performance changes including color fading, aging, transmittance, peeling, hardening, softening, and cracking.
