Q1: What is the primary function of TMG 220 in polyurethane systems?
A: TMG 220 is a tertiary amine-based catalyst designed to promote the urethane reaction (isocyanate–polyol coupling), offering balanced reactivity and improved flow characteristics in flexible and semi-rigid foam formulations.
Q2: Is TMG 220 suitable for water-blown or low-emission foam applications?
A: Yes — TMG 220 exhibits low volatility and minimal odor, making it well-suited for water-blown flexible slabstock foams and other low-VOC systems where operator safety and environmental compliance are priorities.
Q3: How does TMG 220 compare to traditional amine catalysts like DABCO 33-LV?
A: TMG 220 provides comparable gelling activity with reduced volatility and enhanced hydrolytic stability, resulting in more consistent processing behavior and longer shelf life in pre-mixed polyol systems.
Q4: Can TMG 220 be used in combination with other catalysts?
A: Yes — TMG 220 is commonly blended with blowing catalysts (e.g., certain cyclic amines) or delayed-action gelling catalysts to fine-tune cream time, rise profile, and cure development in complex foam formulations.
