(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.

MS密封膠是一種以液體聚硫橡膠為主體，配以硫化組分構成的高性能密封材料口，因具有較優的耐候、耐高低溫性、耐水性、高彈性和高抗位移性，被廣泛用作房屋建筑、高速公路、橋梁、隧道、機場跑道等工程的接縫材料。MS密封膠與硅酮膠相比，具有優異的耐油性能和較低的水蒸氣透過率，是理想的建筑伸縮縫用防水密封材料。事實上，聚硫防水MS密封膠在國內外防水工程中應用的實例很多，如三峽左岸廠房屋面防水工程、新加坡蘇州工業園區凈水廠嵌縫防水、山西萬家寨引黃入晉工程嵌縫防水等。但MS密封膠自身存在的一些缺陷，如粘附性差、強度低、彈恢復率差、固化慢、低溫硫化時間長等。針對MS密封膠存在的缺陷，出現了各種改性產品。研究證明，利用帶有一NCO異氰酸醋端基的氨基甲酸酷預聚物作改性劑和固化劑是提高MS密封膠性能的一個有效途徑選擇合適的填料可以提高MS密封膠的彈性和耐熱性。使用中空微球來降低MS密封膠的密度，考察了不同種類微球及補強填料對MS密封膠密度、拉伸強度、扯斷伸長率、熱老化等性能的影響，研制出具有較低密度綜合性能優異的MS密封膠。http://www.www.mobmib.com/
