(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.

車用膠粘劑/丁基防水嵌縫密封膠按應用部位分類，可分為車身用膠、內飾用膠、發動機底盤用膠、零部件用膠、制造工藝用膠5大類。車用聚氨醋膠粘劑的常見品種及應用如下。
汽車內飾件用水基丁基防水嵌縫密封膠粘劑是指聚氨醋溶于水或分散于水中而形成的膠粘劑，具有不燃、氣味小、不污染環境、節能、操作加工方便等優點。20世紀80年代在國外首見應用于皮革涂飾織物整理和涂料等，直到90年代才逐漸在汽車內飾件粘接上得到應用。水基丁基防水嵌縫密封膠的固含量可以按用戶需要任意調整，茹度也能隨意調節�？梢猿毓袒�，也可熱固化�，F在水基丁基防水嵌縫密封膠粘劑已開始用于汽車一些零部件的粘接，如汽車內飾件PVC人造革、儀表板、擋泥板、門板、地氈和頂棚內襯粘接等。還有如汽車頂棚用PVC薄膜復合氨醋泡沫或織物復合聚氨醋泡沫的軟質頂棚等。
雙組分丁基防水嵌縫密封膠是指應用于受力結構件粘接，能承受較大動負荷、靜負荷，并能長期使用的膠粘劑。用于汽車結構部件的丁基防水嵌縫密封膠粘劑一般是無溶劑雙組分丁基防水嵌縫密封膠粘劑�，F代汽車廣泛采用塑料、聚氨醋材料，丁基防水嵌縫密封膠粘劑是粘接塑料和聚氨醋材料的最好膠粘劑之一。美國Goodyear公司最先成功將雙組分丁基防水嵌縫密封膠用于載重汽車的SMC發動機罩的粘接。隨后美國通用汽車、福特汽車等相繼用丁基防水嵌縫密封膠對大型載重卡車的SMC部件進行粘接，接著又推廣到FRP(玻璃纖維增強塑料)部件的粘接。同時在卡車上用于頂棚、車門、水箱支架、駕駛室頂蓋、車門板等部件的粘接均獲得成功。美國采用聚氨醋系列膠粘劑用于轎車的發動機蓋、駕駛室頂蓋、車門板等零部件的粘接。隨后日本等國也相繼采用了這類技術。近幾年，上�？颠_化工致力于雙組分快速固化型PU丁基防水嵌縫密封膠的開發研究。由于這種雙組分PU丁基防水嵌縫密封膠能快速固化，可以提高生產率。其強度、伸長率等力學性能可按用戶要求調整設計，以滿足更高要求�？梢灶A期這類丁基防水嵌縫密封膠具有很好的應用前景。www.16878m.com
