Can ethylenediamine catalyze the reaction between mercaptan and isocyanate?

Polyurethane catalysts can be divided into two main groups, amine compounds and organometallic compounds. They can be further categorized according to their characteristics, equilibrium and relative efficacy. Traditional amine catalysts are tertiary amines such as triethylenediamine (TEDA, also known as 1,4-diazabicyclo[2.2.2]octane or DABCO), dimethylcyclohexylamine (DMCHA), and dimethylethanolamine (DMEA). Tertiary amine catalysts are selected based on their ability to accelerate the reaction of polyurethanes (polyol + isocyanate, or gel), polyurethanes (water + isocyanate, or bulge), or the trimerization of isocyanates. Since most of the tertiary amine catalysts can accelerate the above three reactions to a certain extent, it is necessary to consider whether they are better for one of the reactions than the other when choosing them. For example, tetramethylbutylenediamine (TMBDA) accelerates gelation more than bubbling. In addition, the simultaneous addition of [[N-[3-(dimethylamino)propyl]-N,N',N'-trimethyl-1,3propanediamine]] and N-(3-dimethylaminopropyl)-N,N-diisopropanolamine balances both the bulging and the gelation reactions, although the former is more powerful than the latter in terms of weight
