(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.

由于單組分室溫硫化硅橡膠已經預混并密封包裝,因此使用時只需要把膠漿擠出,等待其完全固化,即可完成施工。
為了獲得良好的使用效果,使用者需根據丁基防水嵌縫膠的施工對象,提前清潔基材表面的污物及油污,若基材表面需涂底涂劑,則需等待底涂干燥后方可打膠,大多數底涂劑可提高丁基防水嵌縫膠的粘接性,施工前應小范圍地進行相容性測試。
窗玻璃的粘接主要使用非結構性丁基防水嵌縫膠,硅酮密封膠的基礎化合物由硅氧鍵組成,與C-C,C-O,C-N鍵的鍵能相比,Si-。的鍵能最高,為444kJ"mol,如此高的鍵能決定了丁基防水嵌縫膠良好的性能,因此丁基防水嵌縫膠被廣泛地運用到受紫外線照射的門窗玻璃粘接中隨著建筑行業的發展,人們對建筑裝飾材料更加注重美觀和實用性,因此在門窗領域,陽極氧化鋁合金材質的邊框搭配玻璃收到市場的歡迎,也就是大眾口中的“鋁合金窗”。在鋁合金窗剛興起時,用于粘接的是酸性丁基防水嵌縫膠,因酸性丁基防水嵌縫膠的固化速度快,因此酸膠是當時粘接門窗的主流產品,但許多廠商為降低成本,在酸性丁基防水嵌縫膠中加人廉價的聚烯烴類化合物(俗稱白油),因此在使用一段時間后,會出現滲油,影響美觀的同時,密封膠容易脫落。同時,由于酸膠在使用時氣味較大,加之門窗的的升級,鋁合金門窗在高檔裝修中應用得越來越少,隨之酸膠的熱度也不如從前一般。http://www.caffertyclinic.com/
