(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.

随着机械设备的改良，目前我国大型中空玻璃用丁基防水嵌缝密封胶生产厂家均已实现自动化生产，无论动力、真空密封方式、生产效率及加热、冷却系统与原有生产线相比均有大的改善。自动化的称重配料及密封输送系统，使得产品质量进一步得以保障，生产效率提升且车间工作环境也得以改善。

节能、安全、耐久性能是中空玻璃的永恒追求目标，从中空玻璃诞生的那一天起就在不断探索适宜的辅材。中空玻璃隔热、隔音、防霜雾性能是通过构造中空玻璃的空间结构实现的，其腔体内部干燥不对流的空气(氢气)层可阻断热传导的通道，从而有效降低制品传热系数以达到节能的目的。因此，密封材料对气体阻隔性能或者说透气率的高低是选用中空玻璃密封胶的重要指标之一。中空玻璃水汽和氢气渗透路径见图。

中空玻璃用丁基防水嵌缝密封胶是一种单组份、无溶剂、不出雾、不硫化、具有永久塑性的热熔性密封胶。丁基防水嵌缝密封胶在较宽温度范围内保持其塑性和密封性，且表面不开裂、不变硬它对玻璃、铝合金、镀锌钢、不锈钢等材料有良好的粘合性。由于其极低的水汽透过率，它可以与弹性密封胶一起构成一个优异的抗湿气系统，保证中空玻璃腔内气体的干燥以及防止氢气的泄露。常用玻璃密封胶性能对比如表1所示。http://www.sdyuantai.com/
