(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.

硅烷改性聚氨酯密封膠的拉伸粘結強度相對剪切強度的數據對比，硅烷改性聚氨酯密封膠厚度12mm的試件，膠樣A的剪切強度是其拉伸粘結強度的83%;膠樣B的剪切強度是其拉伸粘結強度的87%;膠樣c的剪切強度是其拉伸粘結強度的;硅烷改性聚氨酯密封膠厚度m的試件，膠樣A的剪切強度是其拉伸粘結強度的;膠樣B的剪切強度是拉伸粘結強度的;膠樣c的剪切強度是拉伸粘結強度的79%;總體上來看，同種硅烷改性聚氨酯密封膠試件的剪切強度是小于拉伸粘結強度，其剪切強度與拉伸粘結強度的比值是相近的。這說明同種硅烷改性聚氨酯密封膠的剪切強度相對于拉伸粘結強度的變化是穩定的。

不同厚度試件的最大強度伸長率對比，膠樣A、膠樣B和膠樣c的薄層粘結試件的最大拉伸強度伸長率與常規厚度試件的比值是312%。膠樣A、膠樣B和膠樣C的薄層粘結試件的最大剪切強度伸長率與常規厚度試件的比值是:152%、176%和179%。無論拉伸粘結性測試或者剪切性能測試時，三種硅烷改性聚氨酯密封膠的薄層粘結試件的最大強度伸長率都高于常規厚度試件的最大強度伸長率，其中膠樣B的伸長率最大，膠樣A其次，膠樣C最小。除膠樣C薄層粘結試件與常規厚度試件的拉伸強度伸長率比值達到312%，變化較大外，其余的膠樣薄層粘結試件的最大強度伸長率與常規厚度試件的比值是150%一190%之間，變化幅度相對小一些，同時變化幅度一致。http://www.www.sunsage.net/
