(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.

(1)通过FT-IR和SEM对样品进行表征，结果证明PRPA-MS密封胶成功合成，引步交联结构的形成;TGA分析表明，经PRPA交联改性后的MS密封胶热稳定性有一定程度提升，其最大分解温度由395. 2℃提升至402. 7 0C;水接触角测试表明随PRPA用量的增加，胶膜的耐水性随之增加。

(2)在PRPA含量为2 wt.%时相比较PRPA含量为3 wt.%乳液有着较好的存储稳定性，且PRPA含量为2 wt.%时PRPA MS密封胶胶膜的机械性能良好，其拉伸强度为18.%MPa，断裂伸长率为621. 550;吸水率为10.78，水接触角为88.5;其剥离强度可达3. 879 N/mm，具有一定的应用价值。www.sdyuantai.com
