Abstract: N,N-Dimethylcyclohexylamine (DMCHA) is a tertiary amine catalyst widely used in the production of polyurethane (PU) foams, coatings, adhesives, and elastomers. This article provides a comprehensive overview of DMCHA’s properties, mechanism of action, and influence on the polyurethane reaction profile. It delves into the effects of DMCHA concentration, reaction temperature, and formulation composition on the...
