(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.

综上分析，丁基防水嵌缝胶的耐久性并非简单的材料问题。以聚氨醋类丁基防水嵌缝胶为例，有些丁基防水嵌缝胶能够通过循环老化测试，老化后试样表面无明显变化，仅模量发生微小变化;也有些丁基防水嵌缝胶在经过3个老化循环后就开始出现褪色和开裂。由此可以得出:只要配方调整得当，聚氨醋类丁基防水嵌缝胶也能获得高耐久性能;同样的，如果配方不当，硅酮类丁基防水嵌缝胶也可能耐久性能欠佳。上述结论对硅烷改性类丁基防水嵌缝胶同样适用。

目前，我国尚无针对丁基防水嵌缝胶耐久性的测试方法标准，造成一些从业人员对丁基防水嵌缝胶的耐久性不甚了解。建议参照国际标准，建立我国丁基防水嵌缝胶耐久性的测试方法，为判别胶的耐久性提供依据。同时，各丁基防水嵌缝胶生产厂家也需提高科研投人，研发出高耐久性的丁基防水嵌缝胶产品，终结我国建筑密封材料行业以价格战为主的低水平竞争，为丁基防水嵌缝胶产业升级做出贡献。www.sdyuantai.com
