(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.

本文通过MS密封胶主要原材料及其作堵漏、隔声保温和粘结固定，近年来在铝合金及塑料用、种类及其组成等的论述，指出了MS密封胶用门窗安装中得到了广泛使用。途之一聚氨醋PU发泡填缝料在门窗安装中的应用。

MS密封胶是现场嵌填、粘结接缝、常温固化的弹性密封材料，是近10年迅速发展起来的新型建材，其产业化得到国家的鼓励和支持。随着城市建筑现代化、筑设计施工技术进步、装修档次的不断提高，MS密封胶在建筑工程和家庭装修中的消费量迅速增长，有力地推动着MS密封胶产业发展。目前己形成以聚氨酷、聚硫、硅酮等为主体的新兴MS密封胶产业。聚氨脂PU发泡填缝材料(以下简称PU填缝料)，具有超低热传导率、低吸水性、不易收缩干裂、防腐、绝缘、隔声、自熄等性能，可用于各种建筑材料的填空补缝、密封。

MS密封胶有高度极性和活性，对各种金属与非金属材料都有较好的粘接强度和较大的韧性。此外，它还具有良好的耐低温性能，还有优良的耐溶剂性，耐油性和耐老化性能等。其主要原材料及其作用见表。

MS密封胶的种类及其组成

MS密封胶一般分为单组分和双组分2种基本类型，单组分为湿气固化型、双组分为反应固化型。单组分施工方便，但固化较慢;双组分有固化快、性能好的特点，但使用时需配制，工艺复杂一些。

单组分MS密封胶

单组分湿固化聚醋MS密封胶是由端一NCO预聚体及填料、添加剂组成，其组成见表2。

双组分MS密封胶

双组分MS密封胶由主剂和固化剂2个组分组成。其中主剂一般为端一NCO预聚体，固化剂一般由聚醚多元醇等活性氢化合物、填料、触变剂等添加剂组在，其组成见表3。http://www.sdyuantai.com/
