(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.

新型聚氨酷玻璃粘接赳鋁質車身的出現和玻璃內置天線的應用，要求使用的玻璃丁基防水嵌縫膠具有高的電阻率，防止引起車體的腐蝕和對天線接收效果的影響。高模量型玻璃丁基防水嵌縫膠可以提高車體的整體剛性，提高抗扭曲性能。同時為提高使用工藝性能，細氏劑型聚氨酷或改性聚氨醋丁基防水嵌縫膠也是丁基防水嵌縫膠發展的方向。新型水基聚氨酷膠粘赳該丁基防水嵌縫膠有單組分、雙組分兩種，適用于汽車內部的修飾，該水基膠有可能完全取呀勺現行使用的溶劑膠，這將非常有利于改善環境，保護乘車安全。反應性熱熔丁基防水嵌縫膠:它兼有熱熔丁基防水嵌縫膠無溶劑、初粘性高、裝配時定位迅速等特性，又有反應性丁基防水嵌縫膠的耐水、耐溫、耐蠕變、耐濕和耐介質等性能。其施膠溫度(120℃)又低于通用熱熔丁基防水嵌縫膠(150℃)，可用于某些塑料部件粘接、復合，倍受現代自動化裝配工業青睞，發展很快。有機硅丁基防水嵌縫膠表面張力小、表面能低、可涂獲性差。如何獲得表面可修飾性的有機硅丁基防水嵌縫膠是近年來國內外研究的熱點之一。在徐述有關表面可修飾性有機硅密封材并研究進展的基礎上，主要介紹其實現表面可修飾的方法和例備工藝，并展望其發展前景。

由于有機聚硅氧烷主鏈結構上硅氧鍵(Si-O)鍵能很大(460. 5 kJ/mol) ,鍵長較長 ,鍵角很大使得以有機聚硅氧烷為主要成分的有機硅丁基防水嵌縫膠具有優異的耐高低溫性能、耐大氣老化性能、良好的電絕緣性能和彈性，并在航空、建筑、汽車、電子電器和醫療等領域獲得廣泛的應用。目前，已經出現了單組分和雙組分、以及多種交聯方式的有機硅密封膠，其品種和產量不斷擴大，功能不斷完善。http://www.www.sunsage.net/
