2-Hydroxy-N,N,N-trimethyl-1-propanamine formate is a tertiary amine catalyst used to promote polyisocyanurate reactions (trimerization); 2-Hydroxy-N,N,N-trimethyl-1-propanamine formate provides uniform control of the initiation reaction compared to potassium catalysts.

Product Usage:

Dabco TMR-2 is a tertiary amine catalyst used to promote polyisocyanurate reactions (trimerization). It provides uniform control of the initiation reaction compared to potassium catalysts;

Dabco TMR-2 catalyst is used in rigid foam applications and provides better flow than Dabco TMR catalyst and can also be used in post-curing of flexible molded foam applications.

DABCO TMR-2 is used in polyisocyanurate (PIR) applications but is milder and reduces the release time of rigid foams; it is mainly used in polyurethane rigid foams such as panels, refrigerator composites, etc. DABCO TMR-2 catalyst is a quaternary amine catalyst mainly used in the production of polyurethane rigid foams and has the ability to improve the mechanical and processability of the foams, shorten the curing time of the foams, reduce -NCO residues in the foams, and reduce the -NCO content in the foams. The catalyst is mainly used in the production of polyurethane rigid foams.

DABCO TMR-2 is a quaternary catalyst with low dosage. The catalyst dosage is 1%-5% of the isocyanate. It can be used in various rigid foam systems such as polyurethane and polyisocyanate, etc. It can be used as a high-temperature catalyst by forming an isocyanurate ring at 20°C or higher. It has good mutual solubility with isocyanate and other raw materials.

Storage and transportation:

It should be sealed and stored in dry, cool and ventilated warehouse.


180KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the package cover as soon as possible after the original packaging to prevent moisture and other substances from mixing and affecting the performance of the product. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothes separately and reuse them after washing. Maintain good hygiene practices.
