(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.

丁基防水嵌缝胶能将玻璃和车身牢固地结合成为一个整体，提高车体的刚性及抗扭曲能力，密封性明显改善，安全性、可靠性大幅度增加。同时，这种装配工艺可以减轻车体自重，有利于车体动力学设计。

单组份湿气固化丁基防水嵌缝胶粘接的相对最佳温湿度条件是:温度23 ℃，相对空气湿度50%。一般情况下，对工作场地的温度要求为10一35 ℃，湿度要求为40%一70%。丁基防水嵌缝胶固化过程随时间变化的曲线如图2所示。

由图可知:随着时间的推移，单组份湿气固化丁基防水嵌缝胶的固化速率不断减慢。

技术指标

丁基防水嵌缝胶各项技术指标，见表1。

5拉剪测试

测试依据

拉剪强度测试依据EN 1465。

测试原料

一种丁基防水嵌缝胶，0. 2mm玻璃微珠，样件几何尺寸100mm x 25mm x 1. 6mm(样件长度lx样件宽度W X样件厚度t)的Q235 B钢板样件，样件胶层搭接长度1为12. Smm。按下表要求对样件表面处理，分是不做任何喷涂、只做底漆和面漆。

底涂

使用丁基防水嵌缝胶配套的底涂刷涂，底涂晾置30分钟。
