Product introduction:
UV weathering test chamber is used for the examination of the ultraviolet irradiation resistance capacity when the materials/ products are exposed in ultraviolet irradiation environment. Ultraviolet light is a term used to describe electromagnetic radiation with ultraviolet waves shorter than light visible to humans. UV light is present in sunlight and can cause chemical reactions in certain materials. This reaction caused them to glow, which is called fluoresce. It is widely applied to coating ink, paint, resin, plastics, printing, packaging,aluminum profile,cement, automobile, motorcycle, cosmetics, metal, electronic, electroplating,medicine, etc.

Performance:
* UV test chambers adopt fluirescnet UV lamp which simulate effects of sunlight.
* UV test chambers reproduce wathering damage by UV light, condensing and water spraying.
* UV test chambers is the world's most widely used weathering tester to test types of damages. including color change, gloss loss, weathering, cracking, crazing,blistering, strength loss and oxidation.
