(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.

為適應國內汽車工業發展的需要,單組分聚氨酯密封膠擋風玻璃膠被列為“八五”國家重點科技攻關單組分聚氨酯密封膠新品種開發項目之一。國內最先開發成功該種單組分聚氨酯密封膠的單位他們合作研制的聚氨酯單組分聚氨酯密封膠/密封膠于1993年秋通過省級中試產品成果鑒定,其后ORB-P系列單組分單組分聚氨酯密封膠,并在1998年通過原化工部成果鑒定。
我國聚氨酯擋風玻璃膠的開發應用在上世紀90年代后期得到了快速發展,一方面,國內單組分聚氨酯密封膠行業相關廠家引進國外先進技術和設備投入生產,如引進瑞士Sika公司技術和設備生產的AM-140聚氨酯擋風玻璃膠、引進德國技術和設備生產的聚氨酯擋風玻璃膠、引進德國設備生產的JS-316聚氨酯檔風玻璃膠等;另一方面,國外著名單組分聚氨酯密封膠廠家在國內建立合資企業,將其品牌聚氨酯擋風玻璃膠產品在國內生產,如F502聚氨酯擋風玻璃膠、8590聚氨醞擋風玻璃膠、V3聚氨酯擋風玻璃膠等,此外,還有國外獨資公司的這類產品在國內生產和銷售,像聚氨酯擋風玻璃膠等,總之,聚氨醞擋風玻璃膠的開發應用目前已是一個國內外多品牌產品匯集和競爭的時代。
自上世紀90年代后期以來,單組分聚氨酯擋風玻璃膠的使用性能和工藝性能不斷得到改進提高。使用中取消漆面底膠、只需配用玻璃底膠的單組分聚氨酯擋風玻璃膠,最早的是F502聚氨酯擋風玻璃膠。提高車身剛度的高模數膠、改善鋁結構車身乘坐舒適性和使用耐久性的低導電膠和更易在生產線進行玻璃安裝的瞬時定位型膠,都是開發應用的新品。對于加快該類膠固化速度方面的研究,除改進單組分聚氨酯密封膠主體成分的分子結構和膠的配方以外,還對加熱和能源裝置進行了大量研究,近年來,研究成功遠紅外、微波、高頻加熱裝置,使固化速度成倍加快。最新研發成功的U1201F低溫低濕快固型單組分濕固化聚氨酷擋風玻璃膠,則更適用于生產車間沒有保暖條件的大客車擋風玻璃的裝配。目前單組分聚氨酯密封膠擋風玻璃膠研究、生產和應用呈現向高性能、多品種、系列化發展的態勢。http://www.www.sunsage.net/
