The high content of organic ruthenium catalyst has less foaming and shorter service life. The post-curing effect is slightly inferior to that of organic tin. It is used in the fields of polyurethane synthetic leather, adhesives, elastomers, coatings, and polyurethane foams.

Environmental tin catalyst, no European Union restrictions on nine types of organic tin, used in polyurethane synthetic leather, adhesives, coatings and other fields, activity and dibutyl tin dilaurate similar, no major changes to the formula.

Organic zinc catalyst, less active promoter.

For example, reaction temperatures such as stannous octoate are in the range of 60-65 degrees. Others are also at this temperature distribution. If it is organic cobalt such as cobalt naphthenate, cobalt isooctanoate, etc., the organic tin salt is more active than cobalt. Salt is high. The commonly used T9 is a relatively low temperature.
