DC TMR-2 is a tertiary amine catalyst for the promotion of polyisocyanurate reactions (trimerization reactions). Compared with potassium-based catalysts, it
can control the initiation reaction uniformly;
DC TMR-2 is mainly used in various polyurethane and polyisocyanate and other rigid foam systems, where isocyanurate rings are formed above 20°C.
As high temperature catalyst, it has good mutual solubility with raw materials such as isocyanate.
