(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.

MIL-A-461068和MIL-A-461468丁基防水嵌缝胶规定的技术指标主要分为物理性能、热性能、力学性能、电性能、贮存稳定性等。物理性能主要包括总固体质量分数、施工速率、流动度、黍占度、无粘性时间等。其中，流动度用来表征材料的触变性能，判断在垂直面涂抹丁基防水嵌缝胶是否容易发生流淌，是否会影响工作人员的操作。力学性能包括硬度、拉伸强度、断裂伸长率和剥离强度等。剥离强度是表征丁基防水嵌缝胶粘接效果的重要指标，剥离强度越大，表示丁基防水嵌缝胶粘接性越好。电性能包括体积电阻率、介电常数、介电损耗因子和介电强度，用以表征丁基防水嵌缝胶的电绝缘性能的好坏。

丁基防水嵌缝胶施工不当，不仅会造成经济损失，而且会影响相关部件的功能，从而影响飞机的安全性。单组分RTV丁基防水嵌缝胶的施工一般分为表面处理、涂胶、硫化、修补、清除等步骤。

在需要粘附丁基防水嵌缝胶的地方，应使用合适的溶剂(如乙醇、甲基乙基酮、石脑油等)彻底清洁表面，以去除污垢、油脂等杂质，将表面擦干后再进行涂胶。对于难以粘合的基材，建议使用底漆，即在清洁好的表面上先涂一层底漆，再进行涂胶。www.sdyuantai.com
