What is UV Aging Test?

       The UV aging test uses a fluorescent UV lamp as the light source, and by simulating the UV radiation and condensation in natural sunlight, the accelerated weather resistance test of the material is carried out to obtain the weather resistance result of the material. Ultraviolet aging test is widely used in non-metallic materials, organic materials (such as: coatings, paints, rubber, plastics and their products) to test the degree of aging phenomenon of related products and materials under the changes of sunlight, humidity, temperature, condensation and other climatic conditions and situation.

       When the product is placed in the atmosphere for a period of time, different problems will occur, such as changes in appearance, including cracks, spots, chalking or color changes, and even a decline in performance, which may be due to the loss of molecules in the resin. This leads to changes in the chemical bonds in the molecular structure, mainly caused by sunlight, industrial exhaust gas, bacteria, etc. The aging performance of the product directly affects the use time of the product, so the test of the aging test is of great significance!
