Organic zinc refers to a complex of zinc with an organic ligand (such as zinc gluconate) or a chelating compound (such as zinc methionine). The amino acid zinc chelate has become the primary development trend of the current trace element zinc additive. Organic zinc, such as zinc isooctanoate, has a greater role in rubber, plant feed, feed, and livestock production.
Organotin is a very weakly catalyzed polyurethane catalyst that, in most cases, is not used alone and will be used in combination with organic hydrazine. Organic zinc facilitates construction operations because the weak catalytic nature of organic zinc causes the material to have a long flow period after mixing.
Organic zinc not only catalyzes the reaction of isocyanates with hydroxyl groups to form carbamates, but also promotes other cross-linking side reactions. Although the reaction rate of organic zinc is slow at normal temperature, it is still helpful for the crosslinking of polyurethane and the later increase in strength (post-cure).
