1 slot aluminum double-sealed insulating glass primary seal with butyl rubber, has a very low water vapor transmission rate; secondary sealants are mainly polysulfide and silicone rubber. Polysulfide rubber water vapor transmission rate of less than silicone rubber, UV resistance but not as good as silicone rubber, it applies to window or curtain wall (aluminum frame due to shade, avoid direct sunlight); silicone gel is applicable to hidden frame glass curtain wall, its UV resistance and strength are higher than polysulfide rubber. When the construction of insulating glass with high decorative requirements of hollow glass, the choice of white or transparent silicone rubber.
