催化剂 ,发泡少,使用期较短,后固化效果与有机锡相比略差,用于聚氨酯合成革、胶粘剂、弹性体、涂料、聚氨酯泡沫领域。 High content organic bismuth catalyst , less foaming, shorter service life, and slightly worse post-curing effect than organic tin. It is used in the fields of polyurethane synthetic leather, adhesives, elastomers, coatings, and polyurethane foam.

Environmentally friendly tin catalyst. There are no nine types of organotin restricted by the European Union. It is used in polyurethane synthetic leather, adhesives, coatings and other fields. Its activity is similar to that of dibutyltin dilaurate, and there is no need to change the formula.


苄基三乙基氯化铵


Organic zinc catalyst, low activity co-catalyst.

For example, the reaction temperature of stannous octoate is in the range of 60-65 degrees. The others are also distributed at this temperature. If it is organic cobalt such as cobalt naphthenate, isooctanoate, etc., it is a bit higher. Salt is high. The commonly used T9 is considered to be relatively cold.
