Problems solved by technology

[0004] In order to achieve rapid assembly at the construction site of the vehicle factory, two-component technology is mainly used to improve the curing speed of the product at this stage. Unlike the single-component curing mode from the outside to the inside, the two-component sealant can achieve Curing at the same time, so it has a great advantage in fast curing. However, compared with the operation of one-component, the construction operation of two-component adhesives at the construction site of the vehicle factory is complicated, and the skill requirements for operators are very high. If Failure to meet the technical requirements will lead to poor operation convenience, often a lot of processing time will be wasted in the pre-processing
[0005] The initial bonding strength (4h bonding strength) of the further evolved one-component silane-modified polyether sealant is not high enough in practical applications.
