(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.

测试MS密封胶试样的基础性能情况，以此评估试样的可用性，测试结果如表1所示。由表可知，对比不同MS密封胶试样，可以看出MS密封胶的表干时间最短，而SRMS密封胶的表干时间最长，通常情况下，MS密封胶的表干时间越短越好，因为这意味着胶水能够更快地形成强固的粘接。同时，在3种MS密封胶中，MS密封胶的环保性、耐候性以及弹性等指标均保持较高水平，而其他2组试样针对部分指标性能较弱，可见，MS密封胶基础性能更好。

耐侵蚀性分析

对浸泡后的每组试样进行性能测试，分析每组试样在浸泡完成7d后的表观变化情况，以此验证试样的耐侵蚀性，测试结果如表所示。

由表可知，当3种试样经过无水乙醇浸泡后，在7d内并未发生表观变化问题，说明3种MS密封胶均能够抵抗无水乙醇的侵蚀，而采用90#汽油浸泡时，SR试样、MS密封胶试样表观并未发生变化，但PU试样表面出现轻微膨胀，导致表观变形，当使用10%NaCI溶液浸泡时，SR试样、PU试样均出现了变色，仅MS密封胶在7d内仍然保持良好的质量;同时，采用其他溶液浸泡后，MS密封胶试样表观均未出现严重变化，由此可以看出，MS密封胶的耐侵蚀性能更强，可以抵御更恶劣的外部环境侵蚀。

测试3组试样在不同浸水时间下的粘接性能变化，测试结果如表所示。由表可知，当不同试样经过长时间的浸水试验后，其自身的粘接性能均有所减弱，当每种试样进行4d的浸水测试时，拉伸强度最高的试样为MS密封胶密封胶，其拉伸强度达到0.53 MPa，而其他2组试样均保持在0.35一0.45 MPa之间，当浸水时间达到54 d后，每组试样的拉伸强度均产生明显下降，其中，MS密封胶的拉伸强度下降最大;在3组试样中，MPSU密封胶的断裂伸长率始终保持最高水平，说明该组试样的抗浸水能力较强，同时，随着浸水时间的增加，MS密封胶的粘接破坏面积也并未出现严重增大，为此，MS密封胶的防水性更强。http://www.sdyuantai.com/
