Principle
Use xenon arc light filtered by a filter to perform artificial climate aging or artificial exposure to radiation on the coating. The purpose is to cause the coating to undergo a certain degree of change in the selected properties after it is exposed to a certain amount of radiation energy, or to achieve a certain degree of exposure radiation energy required for the coating to age. The properties selected for testing should be those that are important in the actual application of the coating. The performance of the exposed coating can be compared to the performance of a similarly prepared unexposed coating (control sample).
