(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.

此外，对一该批次车身生产连续性进行了排查。发现该批次车辆均在涂完MS密封胶当天或次日上午便经过了涂胶烘十炉预烘烤，且与面漆喷涂烘烤时间均不超过24 h。MS密封胶涂抹后停留时间相对较短，放置导致受潮的可能性不大。井且，如果因为长时间停产放置导致受潮，应当表现为整车上所有的MS密封胶胶条均有可能出现异常，而不是仅出现在固定的车型以及固定的位置。另外，车门靠轮罩弧度位置的包边MS密封胶胶条开裂呈现出长裂缝(长达10 cm左右)井非胶气泡炸裂产生的短裂缝(一般长度小于1，因此经过上述试验验证和理一沦分析，基本排除MS密封胶材料自身混入空气或者水分、输送系统混入空气或水分以及涂胶后长时间放置导致吸潮的可能性。

现场对左前车门靠近轮罩弧度位置包边MS密封胶宽胶胶条开裂问题发生的序位置进行了进一步摸排，在胶烘十炉出连续观察了10台发现，左前车门靠近轮罩的弧度位置包边MS密封胶宽胶胶条经过胶烘十炉预烘烤后，呈现米自色，包边MS密封胶宽胶胶条外观平整光滑，没有明显开裂的情况，手触包边MS密封胶宽胶胶条发现胶条表十，轻触不会造成胶条变形，但由于未完全烘十固化，使劲按压会变形甚至会出现破裂。面漆烘十炉人日前对上述经胶烘十炉顶烘十的10台车身进行观察发现，缺陷对应位置的包边MS密封胶宽胶胶条在喷涂完面漆后经面漆闪十炉(60--80℃)后仍然没有明显异常。后续又在面漆烘十炉出日对这10台车身进行了后续跟踪，发现经面漆烘十炉烘烤后，左前车门对应弧度位置的包边MS密封胶宽胶胶条均出现了开裂的情况，而且并非固定颜色，脂玉自、琉璃青、雕锡银等颜色均出现包边MS密封胶宽胶条开裂异常，因此判定左前车门靠轮罩弧度位置的包边MS密封胶宽胶胶条开裂问题产生于面漆烘烤冷却的过程中，另外由于各种颜色均有异常，少个且产生包边MS密封胶宽胶胶条开裂的位置固定，其他位置并无明显异常，因此可以基本排除油漆和MS密封胶配套性差导致胶条开裂的可能性。http://www.sdyuantai.com/
