(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.

       为适应国内汽车工业发展的需要,单组分聚氨酯密封胶挡风玻璃胶被列为“八五”国家重点科技攻关单组分聚氨酯密封胶新品种开发项目之一。国内最先开发成功该种单组分聚氨酯密封胶的单位他们合作研制的聚氨酯单组分聚氨酯密封胶/密封胶于1993年秋通过省级中试产品成果鉴定,其后ORB-P系列单组分单组分聚氨酯密封胶,并在1998年通过原化工部成果鉴定。

       我国聚氨酯挡风玻璃胶的开发应用在上世纪90年代后期得到了快速发展,一方面,国内单组分聚氨酯密封胶行业相关厂家引进国外先进技术和设备投入生产,如引进瑞士Sika公司技术和设备生产的AM-140聚氨酯挡风玻璃胶、引进德国技术和设备生产的聚氨酯挡风玻璃胶、引进德国设备生产的JS-316聚氨酯档风玻璃胶等;另一方面,国外著名单组分聚氨酯密封胶厂家在国内建立合资企业,将其品牌聚氨酯挡风玻璃胶产品在国内生产,如F502聚氨酯挡风玻璃胶、8590聚氨酝挡风玻璃胶、V3聚氨酯挡风玻璃胶等,此外,还有国外独资公司的这类产品在国内生产和销售,像聚氨酯挡风玻璃胶等,总之,聚氨酝挡风玻璃胶的开发应用目前已是一个国内外多品牌产品汇集和竞争的时代。

       自上世纪90年代后期以来,单组分聚氨酯挡风玻璃胶的使用性能和工艺性能不断得到改进提高。使用中取消漆面底胶、只需配用玻璃底胶的单组分聚氨酯挡风玻璃胶,最早的是F502聚氨酯挡风玻璃胶。提高车身刚度的高模数胶、改善铝结构车身乘坐舒适性和使用耐久性的低导电胶和更易在生产线进行玻璃安装的瞬时定位型胶,都是开发应用的新品。对于加快该类胶固化速度方面的研究,除改进单组分聚氨酯密封胶主体成分的分子结构和胶的配方以外,还对加热和能源装置进行了大量研究,近年来,研究成功远红外、微波、高频加热装置,使固化速度成倍加快。最新研发成功的U1201F低温低湿快固型单组分湿固化聚氨酷挡风玻璃胶,则更适用于生产车间没有保暖条件的大客车挡风玻璃的装配。目前单组分聚氨酯密封胶挡风玻璃胶研究、生产和应用呈现向高性能、多品种、系列化发展的态势。http://www.sdyuantai.com/
