(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

硅烷改性聚氨酯密封膠高溫下性能穩(wěn)定，低溫下保持柔性和彈性，耐氣候老化、耐水，對玻璃粘接性優(yōu)良，廣泛用于裝飾裝修、防水工程、玻璃安裝和幕墻結(jié)構(gòu)粘結(jié)。1990年前我國基本依靠進口，現(xiàn)建筑市場70%已國產(chǎn)化，年產(chǎn)量超過3萬t。其中脫酸型產(chǎn)品因價位低，占據(jù)較大市場份額。功能產(chǎn)品品種和產(chǎn)量發(fā)展較快。硅烷改性聚氨酯密封膠和玻璃接縫耐候密封膠市場份額增長迅速。中性建筑石材密封膠、防霉密封膠、防火密封膠、金屬屋面及管道密封膠等新的功能產(chǎn)品已開始投放市場。改性有機硅產(chǎn)品正在研制開發(fā)，包括以POP聚醚改性、聚氨酯改性和環(huán)氧共混改性等產(chǎn)品。

該膠種具有抗撕裂、耐磨抗穿刺、對基材不污染、耐酸堿、耐有機溶劑、可涂漆、對石材及混凝土無腐蝕等特性，從而在應用中脫穎而出。硅烷改性聚氨酯密封膠有較好的發(fā)展前景，隨著建筑市場逐步擴大，其需求量將會逐漸增長。此外，由于聚氨酯具有活潑的異氰酸基團，可改性發(fā)展性能價格比更優(yōu)的新產(chǎn)品。但要解決其用于建筑上對混凝土侵蝕、滲油污染、易撕裂、不能涂漆等缺陷，特別是混凝土預制板及石材墻體接縫，機場、道橋混凝土及玻璃纖維增強混凝土施工等結(jié)構(gòu)縫防水密封問題。http://www.m.n5224.cn/
