(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.

采用直接粘接法进行轿车和高档客车挡风玻璃的装配,是现今国内外汽车厂家已普遍采用的一种先进技术。与传统的橡胶密封条固定挡风玻璃的装配工艺相比,它不仅具有固定强度高、密封性能好、外表美观大方等特点,而且具有装配自动化程度高、适合流水线生产作业的优势。单组分湿气固化型聚氨酯粘接MS密封胶是最理想的MS密封胶,这种MS密封胶由美国Essex化学公司于20世纪70年代最先开发研制成功,并作为聚硫橡胶MS密封胶的替代产品最早在美国通用汽车公司得到应用。此后日本Sunstar化学工业株式会社、瑞士Sika公司和法国Revc。公司等相继成功开发应用。
早期的单组分聚氨酯挡风玻璃胶通常需与玻璃底剂和漆面底剂配套使用,经湿气固化后的胶料,要求其粘接剪切强度大于3.5 MPa拉伸强度大于5.0 M Pa断裂伸长率达350%以上,另要求在室温下能快速固化,操作堆积性要好,通常条件下贮存期6个月以上。由于这些独特性能和工艺性能的苛刻要求,加之国内原料和设备的缺乏,研制和生产这种产品非常困难,上世纪80年代后期到90年代初期,国内当时引进车型挡风玻璃的粘接装配所用的单组分聚氨酯密封胶完全靠进口,如的WS-100聚氨酯密封胶车用的是聚氨酯密封胶等。http://www.sdyuantai.com/
