(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.

       随着建筑业的高速发展，越来越多的聚氨酯密封胶化学密封材料取代了原来的水泥、腻子、油灰膏等传统产品而受到市场的青睐。当前，一种新兴的单组分室温湿气固化聚氨酯密封胶(以下简称聚氨酯密封胶)，受到了越来越多用户的喜爱。
       该聚氨酯密封胶主要有以下几方面优点:
       1、这种材料属于溶剂型，固体含量很高，因而在施工时不会出现收缩。同时，良好的弹性密封，使其断裂伸长率可以达到400%以上，弹性恢复率和耐接缝位移性能相对比较出色。
       2、这种材料的极性很高，与绝大多数的基材如大理石、水泥制品、玻璃、铝材、木材、织物等有很好的相容性，连接强度高。普通聚氨酯密封胶的剪切强度不到1兆巴，虽然有些产品的强度可以达到很高，但又失去了弹性，如环氧胶类。而聚氨酯密封胶的剪切强度可以达到2兆巴，且弹性极佳。
       3、该材料在固化过程中因吸收空气中的水分而产生交联，只释放微量的二氨气体，既无溶剂挥发也无渗出物，不会对基材和环境造成污染，因此属于环保型产品。在人们崇尚自然，重视环保的今天，尤其受到欢迎。
       4, PU密封材料为单组分产品，这对于施工人员来说，既节省了操作时间又避免了原料的浪费。
    正是由于该材料同时具有诸多优点，因此可以成为密封剂类产品中的佼佼者，受到人们的普通欢迎。www.sdyuantai.com
