    Abstract

    This study evaluated panel staining around sealed joints using outdoor-exposure and indoor-accelerated staining tests. The outdoor-exposure staining test was performed for one-component silicone sealant (SR-1) and one-component modified silicone sealant (MS-1) at exposure sites in South Korea, Japan, China, and Malaysia. The test specimens were T-shaped sealed joints with artificial marble substrates. The exposure time was four and eight months. In all exposure sites, stains were observed on the panel with the SR-1 sealant after a short time period, whereas MS-1 sealant showed good stain resistance. The indoor accelerated staining tests were performed for SR-1 and MS-1 sealed joints using four staining materials. After an accelerated staining test by the sunshine weather meter, panel staining was performed using three staining materials (the carbon black-dispersed aqueous paste) and a proposed volcanic ash staining material. When the staining water mixed with UNIRANT77 or the proposed powder of volcanic ash was used for the staining test, the stain on the panel joined by SR-1 was greater than that on the panel joined by MS-1.
