Hollow Glass Sealant¡¯s Performance Consider the following elements of glass sealant performance. 1. Ability of anti-gas leak 2. Anti-water permission ability 3. UV capability 4. Anti-water permeable capability 5. Bonding system Glass sealant is very important for Hollow glass system and its stability of structure. Hollow glass always faces the effects of water and gas and temperature. Besides, hollow glass should take double way sealing. The first sealant is preventing water permeation; the second is to keep the stability of structure. So we should use double sealing. |
