(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.

研究了不同MS密封胶与不同涂层系统之间的粘接性，同时，验证了喷漆表面不做打磨处理和打磨处理后粘接性能变化。结果表明，HM120B-4MS密封胶与多种涂层系统粘接性较差，在面漆上涂敷HM120MS密封胶前需进行充分打磨;HM113,HMl123MS密封胶在QH一15+QFS一15B,BFJ一1901一1+BFJ一1901一2,CTN-3728+CTA-3761涂层系统粘接性差，而与QH一15+QFS一15E3,HDY一H06一Y010+HDY一S04-22涂层系统的粘接性好，可不打磨进行涂覆使用;HM317MS密封胶与QH一15+QFS一15B涂层系统粘接适应性好，可不打磨进行涂覆使用;不建议在面漆表面涂敷儿G一103B一2MS密封胶。MS密封胶是飞机上使用的重要功能性材料，目前大量用于机身和机翼整体油箱密封、机身结构密封、气系统密封、座舱密封等。涂料作为一种重要的飞机用非金属材料，由于具有良好的保护性、优良的附着强度、良好的机械物理特性及较优的耐气候性等优点，在飞机上使用主要起到保护、装饰、标和特种功能作用。飞机在服役和使用过程中，可能会受到空气、水分、盐分等外界腐蚀介质影响，从而对飞机结构产生腐蚀损伤。因此，飞机外表面、整体油箱等金属零件部位通常采用涂层系统+MS密封胶的形式进行防护。飞机常规装配工序为零部件表面先喷涂底漆，再涂覆MS密封胶，最后整机活化打磨后喷涂面漆。为了验证MS密封胶与涂层系统的粘接性，需开展相关试验研究。涂料与MS密封胶的粘接性是指它们之间相互附着的能力。良好的粘接性可以确保MS密封胶与涂料紧密结合，防止出现剥落、分层等情况。

无论哪种形式的密封，MS密封胶都会受到各种应力的作用，其中剥离粘接力至关重要。MS密封胶与金属或者其他材料的粘接剥离强度是评定MS密封胶和结构件粘接性能的重要试验项目，是材料研制、产品设计和材料生产质量控制环节中不可缺少的关键性指标。采用180“剥离强度试验方法，根据飞机实际使用工况，在铝合金表面先喷涂涂层系统，再涂覆MS密封胶的试验结构形式，从而验证MS密封胶与涂层系统的粘接性，为飞机结构设计和材料选用提供可靠的性能数据。http://www.sdyuantai.com/
