Weatherability Testing is the use of solar carbon arc lamp (irradiation amplitude of AC voltage 50V, ACcurrent 60A), simulate the products under the condition of combination with ambient temperature andhumidity, its adaptability and the characteristics such as cracking, damage and other changes in thetest.Car paint is usually exposed to the outside in some form, exposed to ultraviolet, rain, frost, oxygen,heat and other chemical, physical, optical erosion. Weatherability testing, in terms of our glass coatingappearance of the gloss, adhesion, hardness and other performance, to test the tolerance under theenvironment surrounding by impact factors and erosion.Evaluate the products through the test results withthe difference between before and after, it is an important test for the weatherability evaluation.
