(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.

Information
MS密封膠施工溫度要求在5℃一40℃范圍內(nèi)。基材表面溫度過(guò)高可能造成固化反應(yīng)速度過(guò)快，產(chǎn)生的水分子物質(zhì)來(lái)不及遷移出膠體表面在內(nèi)部聚集形成氣泡，破壞膠縫表面的美觀;溫度過(guò)低固化過(guò)程顯著延長(zhǎng)，受溫差影響熱脹冷縮造成外觀走形。溫度太高與太低均不宜進(jìn)行MS密封膠的施工，容易造成MS密封膠在固化過(guò)程一直處于拉伸或壓縮狀態(tài)，固化后內(nèi)部應(yīng)力超過(guò)設(shè)計(jì)的位移能力造成內(nèi)聚或粘結(jié)破壞，導(dǎo)致密封失效產(chǎn)生滲漏。
接縫密封必須使用閉孔型聚乙烯類或開孔型聚氨醋類泡沫棒作襯墊，避免MS密封膠造成三面粘結(jié)并有效地控制接縫中MS密封膠嵌人深度和形狀，使MS密封膠完全潤(rùn)濕兩側(cè)基材表面，讓MS密封膠發(fā)揮最佳的位移能力。泡沫棒襯墊未按規(guī)范施工可能破壞膠縫表面的美觀，泡沫棒填塞應(yīng)平直，并按設(shè)計(jì)要求預(yù)留打膠厚度。泡沫棒太大容易被拉得太緊時(shí)，密封后回縮拖動(dòng)MS密封膠，使不規(guī)則的長(zhǎng)條狀向外凸出，影響觀感。www.kubee.cn
