(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.

中空玻璃丁基防水嵌缝胶失效的原因，中空玻璃丁基防水嵌缝胶失效的直接表现是中空玻璃内框里有水汽凝露(结雾)时。结雾是由于水汽扩散进人边缘丁基防水嵌缝胶导致干燥剂吸水饱和而引起的。目前，多功能的中空玻璃经常充填特殊气体，如惰性气体，目的是提高它们的隔热和或隔音质量。中空玻璃内的气体和环境中的空气会存在部分微小的压差，这会引起它们扩散，结果会导致中空玻璃内的气体被空气稀释。充填气体的稀释会影响中空玻璃的性能，使得其隔热和隔音质量降低。因此，边缘丁基防水嵌缝胶的质量极大影响了中空玻璃的使用寿命和性能。

中空玻璃暴露在多种环境因素下，例如温度和大气压力波动、风压、工作荷载、阳光、水和水汽等，这些会负面影响中空玻璃的平均寿命。由不同环境因素引起的应力不是简单的叠加，它们的相互作用导致了不均匀的应力作用在边缘丁基防水嵌缝胶上，出现所谓的合力现象。研究证实，水、高温和阳光的同时作用会对中空玻璃的边缘丁基防水嵌缝胶产生最大的应力。这种降解效果在丁基防水嵌缝胶与玻璃界面是最显著的，是经常导致有机丁基防水嵌缝胶部分或完全豁结性失败的原因。影响中空玻璃寿命的因素很复杂，虽然丁基防水嵌缝胶系统本身的耐久性和有效性是非常重要的，但最基本的还是丁基防水嵌缝胶对玻璃与间隔条材料的粘结性，造成中空玻璃丁基防水嵌缝胶失败的主要原因也是丁基防水嵌缝胶与玻璃之间粘结脱落。各类丁基防水嵌缝胶的水汽渗透率MVTR、渗透率、透气性(氢气)。http://www.sdyuantai.com/
