(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.

随着科技的发展，一些新材料、新技术不断涌现，要不断探索和使用新的材料和技术。历史地看，新材料、新技术的应用，往往会带来高效率、高可靠性和低成本等。例如，单组分湿固化PU粘接/丁基防水嵌缝胶替代橡胶条用于汽车玻璃装配，就是玻璃装配技术的一场革命。

安全环保原则

由于车辆不同于一般的静态商品，在选用粘接/丁基防水嵌缝胶时，要充分考虑车辆行驶工况。由于地理环境的变化，车辆又会经受严峻的气候考验，所以粘接/丁基防水嵌缝胶应能满足其长期服役环境下的要求。

只注重粘接/丁基防水嵌缝胶的自身特性，忽视了施工的要求。由于粘接、丁基防水嵌缝胶的化学基料有所不同，被粘接密封的材料也多种多样，再好的丁基防水嵌缝胶也应结合基材进行选择和试验。必要时应选择处理剂，确保粘接可靠。

只顾生产线要求，忽视了材料特性。汽车生产线均存在生产节拍的问题，每个工位压缩1 min就有可能增加数百台车的产量。但粘接/密封材料应用在汽车上往往需要一定的反应固化时间，否则达不到良好的效果。例如:单组分PU的固化时间较慢，一般每24 h固化3-5mm，且其固化剂是水分，如果在较短的时间内进行淋雨试验，一方面会因胶固化未达到一定的厚度，将粘接/丁基防水嵌缝胶冲坏;另一方面可因胶在固化过程中接触到大量的水，反应速度加快，容易使丁基防水嵌缝胶的致密性变差，产生气泡，强度和密封性降低。http://www.sdyuantai.com/
