(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.

    建筑用硅烷改性聚氨酯密封胶的质量好坏需要用检测方法来确定。当检测出硅烷改性聚氨酯密封胶具有持久的粘结性、适当的位移能力、一定的模量、耐久性及较低的热失重时,则认为是高质量的产品。在建筑用硅烷改性聚氨酯密封胶(不包括结构胶)的使用中,其与基材有无持久粘结性关系到建筑物漏水、保温、节能等问题。伸缩性良好的材料意味着较低的模量和良好的位移能力;同时较低模量的硅烷改性聚氨酯密封胶和基材表面在拉伸时会对接口产生较小的应力,对硅烷改性聚氨酯密封胶的持久粘结性有利。因此良好的位移能力代表硅烷改性聚氨酯密封胶不易因为单元板片接口位移量过大而开裂。目前市场上的建筑用硅烷改性聚氨酯密封胶种类繁多,质量却参差不齐,尤其是生产厂家不成熟的配方和随意降低成本,使得产品抗老化性能和粘结能力明显降低。因此,检测机构和生产厂家有责任把握建筑用硅烷改性聚氨酯密封胶的质量,完善检测项目,避免使用劣质产品而给幕墙工程带来不可弥补的损失。www.sdyuantai.com
