Q1: What is the primary function of TMG 612 in polyurethane systems?
A: TMG 612 is a highly selective tertiary amine catalyst designed to promote the urethane reaction (isocyanate–polyol coupling) while providing balanced control over gelation and blowing kinetics. It is especially valued for enabling fine-tuned reactivity profiles in flexible and semi-rigid foam formulations.
Q2: Is TMG 612 compatible with moisture-cure or one-component PU systems?
A: Yes — TMG 612 exhibits good compatibility with one-component moisture-curing polyurethane systems, where it helps accelerate film formation and improve through-cure without significantly compromising pot life under ambient conditions.
Q3: How does TMG 612 compare to traditional amine catalysts like DABCO 33LV in terms of odor and volatility?
A: TMG 612 features lower volatility and reduced amine odor compared to many conventional liquid tertiary amines, contributing to improved workplace handling and lower VOC emissions during processing — making it suitable for applications with stricter environmental or occupational exposure considerations.
Q4: Can TMG 612 be used in combination with other catalysts?
A: Yes — TMG 612 is commonly blended with complementary catalysts (e.g., metal carboxylates or delayed-action amines) to achieve tailored cure profiles, particularly in complex molded or integral-skin foam applications requiring precise control over demold time and surface set.
Q5: What are the recommended storage conditions for TMG 612?
A: Store in tightly sealed original containers at temperatures between 5 °C and 30 °C, away from direct sunlight and strong oxidizing agents. Prolonged exposure to high humidity or elevated temperatures may affect catalytic consistency over time.
