Q1: What is the primary function of TEGOAMIN SMP in polyurethane systems?
A: TEGOAMIN SMP is a highly selective, non-volatile tertiary amine catalyst designed to promote the urethane reaction (isocyanate–polyol coupling) while minimizing side reactions such as trimerization or hydrolysis. It supports balanced reactivity and improved processing control in flexible and rigid foam formulations.
Q2: Is TEGOAMIN SMP compatible with water-blown and MDI-based systems?
A: Yes — TEGOAMIN SMP demonstrates good compatibility with both water-blown and MDI-based polyurethane systems, including those used in slabstock, molded foams, and integral skin applications. Its low volatility and thermal stability support consistent performance across diverse process conditions.
Q3: How does TEGOAMIN SMP compare to traditional amine catalysts in terms of odor and fogging behavior?
A: As a non-volatile, high-molecular-weight amine derivative, TEGOAMIN SMP exhibits significantly reduced volatility compared to low-molecular-weight amines. This translates to lower potential for odor generation and minimal fogging in automotive and interior applications where emissions are critical.
Q4: What is the typical dosage range for TEGOAMIN SMP in PU foam formulations?
A: Dosage depends on formulation requirements and desired reactivity profile, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the total polyol component. Optimization should be performed through lab-scale trials under representative processing conditions.
