(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.

从表中可以看出,高强度MS密封胶的挥发性有机物含量偏低,可以满足汽车制造的环保要求。所以,利用高强度MS密封胶代替挥发性有机化合物含量超标的聚氨酯密封胶,与环保可持续发展理念相符。
汽车的前挡风玻璃在发生碰撞的时候,要求最大粘接强度为0.2MPa,最大剪切强度为0.37MPa。而大巴车则要求最大粘结强度为0.38MPa,剪切强度为0.09MPa。高强度MS密封胶与聚氨酯密封胶的修补后强度具体如表5所示。
从表可以看出,在自修和交叉修的基础上,高强度MS密封胶与聚氨酯密封胶的粘接强度和剪切强度都明显大于汽车与大巴车碰撞时候随需要的最大粘接强度与剪切强度,这代表两者都可以满足前挡风玻璃维修胶粘剂的使用要求。
高强度MS密封胶与聚氨酯密封胶基本性能测试结果具体如表6所示。
从表中可以看出,高强度MS密封胶与聚氨酯密封胶的基本性能比较接近。http://www.sdyuantai.com/
