(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.

当MS密封胶试样经旋转载度计法测试后，材料呈现未固化状态，因此需要停放一段时间，测试停放过程中MS密封胶试样的粘接强度，以此分析每组MS密封胶试样的粘接能力，测试结果如图2所示。

由图2可知，随着MS密封胶试样停放时间的延长，MS密封胶试样逐渐固化，使其粘接强度逐渐增高，当停放时间在6h以内时，每组MS密封胶试样的粘接强度变化并不明显，而当停放时间在6h以上时，每组MS密封胶试样的粘接强度呈上升状态，其中，M3 ,M4组MS密封胶试样粘接强度上升幅度较大，说明这两组MS密封胶试样的粘接能力相对较高，而当停放时间达到24 h时，M4组MS密封胶试样的粘接强度达到1. 8 MPa左右，在4组中保持最高状态，说明M4组试验粘接效果好。

拉伸粘接强度分析

分析每组MS密封胶试样在拉伸过程中的拉伸粘接强度变化，测试结果如图3所示。

由图3可知，在MS密封胶试样拉伸过程中，每组MS密封胶试样的拉伸粘接强度会在拉伸初期呈小幅度上升，随着拉伸时间延长，每组MS密封胶试样的拉伸粘接强度则会迅速下降。在4组MS密封胶试样中，M1,M2,M3组MS密封胶试样的拉伸粘接强度始终低于M4组，而M4组MS密封胶试样拉伸粘接强度最高达到4. 5 MPa左右，因此，在进行拉伸测试时，M4组MS密封胶试样的粘接能力最强。http://www.sdyuantai.com
