(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.

a.使用聚氨酯密封胶的连接部位，拆卸后再组装时必须使用新胶液。

b.对于间隙、不平度较大的结合面，单独使用聚氨酯密封胶时防漏效果较差。

c.尺寸恢复胶需一定的喷镀设备，较难普及与推广。

d.使用不当会带来不利。如燃油系统各油管接头面，如果涂层过厚或四周乱涂，紧固后多余液体易被冲人燃油管道，甚至进人喷油泵、喷油器，造成发动机转速不稳、偶件咬死、柴油机熄火等故障。如果润滑系统各接头、螺纹、盖板纸垫处涂得过多，容易使胶液进人润滑系统，加剧运动副磨损，引起机油变质。同时，使用聚氨酯密封胶过多不易涂匀，会增加渗漏可能，只有正确使用才能达到预期效果。www.sdyuantai.com
