(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.

       目前市場上常用的MS密封膠按組成化學成分不同可分為:硅酮MS密封膠(SR)、改性硅酮MS密封膠(MS) ,聚氨酷MS密封膠PU) ,聚硫MS密封膠(PS);按組分不同，又可分為單組分和雙組分(或多組分)MS密封膠;按照位移能力不同，又分為50,35,25 ,20四個級別，其中四個級別的建筑MS密封膠按拉伸模量還分為低模量(LM)和高模量(HM)兩個次級別;按照流動性不同又分為非下垂型和自流平型;按照固化時釋放的小分子物質不同，又可分為酸性膠、中性膠，中性膠又分為脫醇型膠、脫酮厲型膠。

       改性硅酮MS密封膠和聚氨酷MS密封膠的粘接性高于普通硅酮MS密封膠。裝配式混凝土墻體構件是一種表面呈多孔、不規(guī)則、且呈堿性的基材，對普通硅酮MS密封膠來說屬于難粘材料，因此不能直接選用普通的硅酮膠填縫膠來作為混凝土板塊填縫。另外要值得特別注意的是:一款膠并不能保證對所有基材都要良好的粘接性，即使同樣的基材，不同表面處理方式會使MS密封膠的粘接效果不一樣;甚至是同樣的基材、同樣的表面處理方式，不同廠家的MS密封膠粘接效果也大不相同;因此在MS密封膠使用之前應進行粘接性測試，以便選擇合適的產品。http://hbxqtax.com/
