Information

First, the organic ruthenium catalyst is also called neodymium neodecanoate. Organotin catalyst: also known as dibutyl tin dilaurate

In terms of appearance, organic ruthenium catalysts and organic tin catalysts are used. Appearance was light yellow transparent slightly viscous liquid and yellow transparent viscous liquid. No antioxidants are added during the production process and the color is deeper than the organotin catalyst.

The effective antimony content of organic germanium is 19.5-20.5%, and the effective tin content of organic tin is 18.0-19.0%.

The characteristics of the first organic germanium and organotin catalysts are different: organic germanium does not resist hydrolysis, has high catalytic activity, has a certain selectivity for the reaction of hydroxyl groups with isocyanate, and is highly toxic. Organotin has a weak catalytic activity, a higher catalytic selectivity than DY-12, a lower product bubble, and low toxicity and environmental protection.

The second uses are mainly used in coatings, polyurethane foams, elastomers, adhesives, elastomers, synthetic leather resins.

The third aspect of environmental protection: organic germanium does not meet EU export standards, organic tin meets EU export standards.
