(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.

四川某医院大楼，隐框玻璃幕墙使用白云牌丁基防水嵌缝胶，建于2005年。幕墙服役14年时调研结果:丁基防水嵌缝胶硬度在4446之间，与基材粘结良好。至今，幕墙已服役17年，使用状况良好，未出现任何失效状况。

广州某广场，隐框玻璃幕墙，建于1996年，幕墙服役24年时调研结果:隐框玻璃幕墙丁基防水嵌缝胶与基材粘接良好，硬度适中，弹性仍然很好，可以继续使用。

深圳某大楼，隐框玻璃幕墙，建于1998年，幕墙服役19年时调研发现:隐框玻璃幕墙丁基防水嵌缝胶与基材粘接良好，硬度在3 746之间，硬度范围较大，但丁基防水嵌缝胶总体状况仍较好。

此次调研中，其中7个项目丁基防水嵌缝胶有一定程度的老化(丁基防水嵌缝胶非白云品牌)，丁基防水嵌缝胶硬度增加、弹性下降;部分典型项目具体调研结果如下。

深圳某大厦，隐框玻璃幕墙，建于1992年，幕墙服役24年时调研结果:隐框玻璃幕墙丁基防水嵌缝胶已经基本硬化，弹性比较差。

上海某广场，半隐框玻璃幕墙，建于1999年，幕墙服役23年时调研结果:半隐框玻璃幕墙丁基防水嵌缝胶与基材粘接良好，还有一定的弹性，但硬度上升明显，超过600。

杭州某广场，半隐框玻璃幕墙，建于1999年，幕墙服役23年时发现:半隐框玻璃幕墙丁基防水嵌缝胶与基材粘接良好，硬度超过60，弹性一般。

另外，有4个项目丁基防水嵌缝胶老化情况比较严重(丁基防水嵌缝胶非白云品牌)，部分典型项目具体调研结果如下。

广州某隐框玻璃幕墙项目，幕墙服役22年时对其丁基防水嵌缝胶进行检测和取样。经检测，硬度为30，弹性尚可。采用“重新粘结法”测得标准条件下的拉伸粘结强度平均值为O.SSMPa，不满足GB 16776中标准条件下拉伸粘结强度不低于0.60MPa的要求，已对幕墙安全造成威胁。http://www.sdyuantai.com/
