TMR-2
Product Overview:
TMR-2 (CAS 62314-25-4) is a delayed-action quaternary ammonium trimerization catalyst specifically designed for PIR and rigid polyurethane foam systems. It is widely used in insulation panels, cold-storage boards, refrigerators, and high-index PIR formulations because it provides controlled trimerization, improved processing, and enhanced foam performance.
