(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.

以3一异氰酸醋基丙基三甲氧基硅烷(MSN)和二乙二醇合成了含有醚键的硅烷偶联剂，并以此制备的硅烷改性聚氨酯密封胶具有良好的透光性。用作建筑硅烷改性聚氨酯密封胶使用时，外观上具有良好的通透性，能够使建筑在视觉上满足美观的需求。

制备的硅烷改性聚氨酯密封胶，通过改变配制过程中所用无机填料的型号来改善硅烷改性聚氨酯密封胶的透明性，助剂与密封胶体系的相容性等匹配。硅烷改性聚氨酯密封胶的透明性由填料疏水性气相二氧化硅表现，所得密封胶具有较高透明度。

以聚丙二醇(PPG)和N, N'-淡基二咪哩(CDI)为原料合成聚醚，并与含氨基的硅烷偶联剂进行反应，合成了具有较低模量的硅烷改性聚醚树脂。所得树脂的力学性能优异，适用于低模量的装配式建筑以及家装防水等行业。

充分利用和结合了不同成分之间理化性质的协同作用，制备了一种单组分硅烷改性聚氨酯密封胶，具有低模量的效果。通过调整配方制备了硅烷改性聚氨酯密封胶，在具有较低模量的同时具有极高的断裂伸长率，应用于建筑装配领域。制备了低模量高茹附装配式建筑用硅烷改性聚氨酯密封胶，通过添加特定结构端经基支化聚醚、支化聚醚环氧树脂以及中空玻璃微球等填料，改善了硅烷改性聚氨酯密封胶的粘接性，同时具有低模量。通过在硅烷改性聚醚中引人大分子单官能团聚醚，降低了硅烷改性聚氨酯密封胶的模量、增加回弹性。通过调整制备工艺及配方，获得了低模量、低茹度的环保型硅烷改性聚氨酯密封胶。

制备了一种硅烷改性聚氨酯密封胶，以硅烷改性聚醚为原料，通过调整硅烷改性聚醚树脂的相对分子量分布的集中度，选择出适宜的原料，使得制备得到的硅烷改性聚氨酯密封胶具有低模量和高弹性;通过加人低茹度的小分子物质降低其茹度，为同时保证最终硅烷改性聚氨酯密封胶的弹性恢复率不下降，以聚醚多元醇PPG5616为降茹剂，获得了低模量、高弹性的硅烷改性聚氨酯密封胶;同时调整填料、偶联剂的种类，并加人防霉剂，最终获得了一种低模量、高弹性、高挤出性和防霉的硅烷改性聚氨酯密封胶。http://www.sdyuantai.com/
