(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.

胶粘剂和聚氨酯密封胶都以粘接为基本特征，由这共同点可将它们归为同一类。它们的基本区别如下:起源不同，最早的胶粘剂是树胶、浆糊等，而聚氨酯密封胶源于桐油灰、沥青。主要功能有明显差别，胶粘剂以粘结两材料为主要目的;聚氨酯密封胶主要是嵌缝、密封、堵漏。胶粘剂以实现界面粘接的强度为特征，在应力作用下一般呈现为刚性，接头直至断裂(胶层内聚破坏或被粘材料破坏)基本不发生显著位移，即不做功;聚氨酯密封胶以实现密封为主要特征，与界面粘接并在受力时呈现弹性或弹塑性，在应力或交变应力下接头不改变体积但可改变形状，可在一定范围内伸缩运动、位移且不发生破坏(不论内聚破坏或被粘材料破坏)，即做功，更接近橡胶弹性材料。早期聚氨酯密封胶分类于胶粘剂，但随着产品品种、产销量不断增长，其应用范围越来越广泛。

胶粘剂有的可用于墙面与壁纸的粘贴，有的用于构件联结和锚固，甚至有用于飞机机翼及旋翼结构件的粘结;聚氨酯密封胶可用于墙体接缝的防水、用于游泳池、储油池接缝防渗漏，甚至有的用于飞行器的接缝密封，同时还可用于弹性粘结，如玻璃与玻璃的粘结、玻璃与金属框架的粘结，汽车饭金与车身的弹性粘结。由此可见，胶粘剂和聚氨酯密封胶是功能性材料，材质和性能设计是依据不同的用途要求，也就是说各个材料都具有局限的适用范围。所以选择和应用这类材料，首先应明确它们的基本定义、分类、功能和要求。www.sdyuantai.com
