Description
NT CAT TMR-2 is a tertiary amine that promotes the polyisocyanurate reaction. It provides a uniform and controlled rise profile compared to potassium based catalysts. NT CAT TMR-2 is used in rigid foam applications where improved flowability compared to TMR catalyst is required. It can also be used in flexible molded foam applications for back end cure.
Applications
NT CAT TMR-2 is suitable for all types of polyisocyanurate foam systems. It is typically used in combination with a polyurethane-type catalyst.
NT CAT TMR-2 is somewhat delayed compared with TMR catalyst, and initially more reactive than TMR-3 catalyst. TMR-4 catalyst, in particular, was specifically designed to enhance the flowability of isocyanurate systems.

Storage information
NT CAT BDMAEE catalysts can be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30 °C. Lower and higher storage temperatures are not preferable and should be avoided.
