(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.

忽视对基材表面的处理。对粘接/MS密封胶的使用，目的是为了将被粘物牢牢地结合在一起。实践证明，绝大多数粘接/MS密封胶要求对基材进行表面处理，如要除去基材表面的灰尘、油污、水分等。对于经过模塑成型的产品，还要用溶剂除去表面的低分子物质;对于特别光洁的材料，表面还要做打毛处理等，以利于粘接密封效果。

忽视施工环境对粘接效果的影响。多数粘接/密封材料，都有适宜的环境温湿度要求。如，在寒冷或过热的环境下施工，即使同一产品也会产生不同的粘接效果。特别是对湿气固化类产品，其固化速度和效果对温湿度的要求较高，否则就容易产生固化缓慢或易鼓泡现象。

忽视人员培训。良好的人员素质和严格按照操作指南进行施工，是取得良好施工效果的重要条件，也是避免施工质量不稳定的重要措施之一。

近年来，随着汽车工业的发展和人们对环保性要求的提高，对车用粘接/密封材料也提出了更高的要求:

快速固化。由于生产效率的提高和流水线的要求，能快速固化的粘接/密封材料越来越受到青睐，特别是受外界环境影响小、操作简便的粘接/密封材料有着广阔的市场需求;

阻燃性。随着汽车轻量化和化工新材料的应用，车辆上非金属材料越来越多，仅粘接密封材料，单车用量可达几公斤到几十公斤，一旦失火，非常容易燃烧，所以阻燃型粘接/密材料将成为发展的必然趋势;

环保性。粘接/密封材料中往往含有一定量的溶剂，在施工过程中及车辆服役期内均会自由挥发，轻者在施工现场容易导致人员不适，重者可能对人体产生危害，所以无溶剂、低析出、无污染的环保型粘接/密封材料为人们所期待。http://www.sdyuantai.com/
