(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.

丁基密封膠流淌造成中空玻璃污染而失效,行業內俗稱“丁基密封膠流淚”現象。該現象產生的原因主要有以下兩點:
①
摻油的密封膠如硅酮中空膠、耐候膠等所含的低價添加劑一一礦物油,滲透至丁基密封膠內,使丁基膠軟化甚至溶解而流淌至中空玻璃內表面。
②
丁基密封膠加入了過多的低分子量基料,造成材料軟化點低,在高溫條件下(如南方夏季太陽照射下)產生流淌。這種現象最大的特點是滯后性,一般在中空玻璃上墻使用后一段時間才出現,因此危害巨大。
例如華東地區一幕墻工程,使用不到兩年,中空玻璃因丁基密封膠流淌而失效,最后不得不全部更換,給相關責任方造成了極大的經濟和信譽損失。所以淄博元泰密封膠有限公司提醒廣大丁基密封膠用戶采購時一定選擇產品質量好,業內信譽高的丁基密封膠生產廠家,不要一時貪圖丁基密封膠價格便宜而吃虧,導致造成工程質量問題,十多么不值啊。
