In many climatic conditions, there is UV ray, which is called ultraviolet rays, which has the greatest effect on sealing materials. Because UV has high energy, it changes the internal structure of polymer and causes quality deterioration. In addition, temperature, humidity, and rainfall, snowfall, and atmospheric pollutants are also factors to be avoided in maintaining the integrity of the sealant. In this study, we tried to obtain reproducibility by using a composite deterioration test device which can describe the environment of the outside air as a part of the research project to investigate the weather change in the prototype of the structural sealant. The outdoor exposure test result and the composite deterioration test device Correlation analysis. In the future, it will be possible to predict the changes in the physical properties of the structural sealant by applying the composite deterioration test equipment and outdoor exposure test data.
