(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

Information
盡管中模量丁基防水嵌縫密封膠極限強度有限，但仍可長期承受窗戶中三層中空玻璃或建筑物結構性裝配中大玻璃單元的重量，這主要歸功于丁基防水嵌縫密封膠出色的彈性回復能力和高位移能力。此外，丁基防水嵌縫密封膠甚至可以吸收玻璃和窗框間不同熱膨脹形成的位移。因此，丁基防水嵌縫密封膠在風化和循環應力的組合作用下，往往表現出比其他丁基防水嵌縫密封膠更優的性能。
丁基防水嵌縫密封膠耐久性不過關，過早老化，導致的能量損失遠大于生產丁基防水嵌縫密封膠所需的生產鏈能耗。
美國匹茲堡于1958年落成的美國鋼鐵工人聯盟大樓是第1批用丁基防水嵌縫密封膠密封的建筑物之一，底特律于1971年建成的SH&G大樓是第1座采用丁基防水嵌縫密封膠全隱框結構性裝配的幕墻建筑物，這兩個建筑物至今均未出現丁基防水嵌縫密封膠質量問題�？梢�，丁基防水嵌縫密封膠出色的彈性回復能力和高位移能力能夠保證其在建筑粘結和密封領域應用的超長壽命。
用其他丁基防水嵌縫密封膠代替組角膠在型材組角時使用。
細縫膠在型材450角斷面起密封作用，防止雨水從斷面細縫滲人型腔內。細縫丁基防水嵌縫密封膠是專門針對細縫設計而生產的一種丁基防水嵌縫密封膠，由于細縫與普通面板接縫所需丁基防水嵌縫密封膠的強度及延伸率不同，不能用普通耐候丁基防水嵌縫密封膠代替細縫丁基防水嵌縫密封膠進行使用。
由于型材尺寸大，組裝精度及質量要求又比較高，因此組角前也可采用螺釘臨時定位固定，并設置一些工裝來保證其組角平整和接縫緊密。www.www.lustload.com
