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.

This paper describes the evaluate adhesion area effects on structural performance of structural sealants. In this experimental, glass panel thickness and initial construction depth of sealant are 12 and 5mm. Principle variable is addition of sealants : 5, 10, 15mm. Prior to add sealant, adhesion part carried out cover with primer. Test method is based on the bending test. Loading method is to put sand on the center of the glass panel in order to the wind load applied to the actual condition. Test results indicated that addition of sealants is not improve the peak load.
