10 1 the naming of glue

The name 502 comes from its constituent name, and only China has this name: Europe and the United States basically call it super glue, while Japan calls it instant after instant, and there is no name 502.

After checking 10 1 glue, most of the comments said that its composition is not much different from that of 502, but a chemical industry forum said that its composition is the same as that of 502 polyurethane group, but its side chains are different, so it can be classified as one category. As for the origin of the number 10 1, there is no credible statement. One possibility is that other manufacturers produce glues with similar chemical structure, and take other names as the difference of product identification.
