(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.

国外汽车生产中使用硅烷改性聚氨酯密封胶的历史始于20世纪30年代。硅烷改性聚氨酯密封胶在汽车制造过程中虽然只是辅助材料，但是由于这类材料的应用可以简化生产工艺、节省材料的使用量、增加部件的强度，尤其是在防振、隔热、防腐、防锈、防松、防漏、降低噪音、减轻自重、提高汽车的舒适性和安全性等方面有着特殊的作用，已经成为现代汽车工业生产中必不可少的材料。

我国汽车工业在20世纪80年代时还比较落后，密封胶的应用尚得不到普遍的重视，用胶品种少，用胶量也不多。随着我国汽车工业快速发展，硅烷改性聚氨酯密封胶应用水平也上了一个台阶，进入21世纪后，全国粘接/硅烷改性聚氨酯密封胶的生产厂家已超过1 800家，产品牌号有4 000多个。

车用硅烷改性聚氨酯密封胶的选用原则

功能首选原则

尽管硅烷改性聚氨酯密封胶的功能有5个方面，但在具体应用时，会有其中的某一项或几项成为考虑的重点。对汽车粘接/密封胶的要求见表2。

经济适用原则

根据部位要求的不同，只要能满足要求，可以选择不同种类的硅烷改性聚氨酯密封胶，以降低采购成本。也就是说根据功能要求对使用部位进行细分，同样是粘接/硅烷改性聚氨酯密封胶，应用于风挡玻璃、车身与骨架、地板与骨架的粘接要求是不同的。对要求不高的部位，则可以选用低成本硅烷改性聚氨酯密封胶。http://www.sdyuantai.com/
