Q1: What is the primary function of TEGOAMIN B 75 in polyurethane systems?
A: TEGOAMIN B 75 is a tertiary amine catalyst specifically designed to promote the urethane reaction (isocyanate–polyol coupling), enhancing gelation and improving processing control in flexible and rigid PU foams, coatings, and adhesives.
Q2: How does TEGOAMIN B 75 differ from other amine catalysts like DABCO or DMCHA?
A: Unlike strongly volatile or highly reactive aliphatic amines, TEGOAMIN B 75 offers balanced reactivity with reduced volatility and lower odor impact. Its molecular structure provides improved compatibility with hydrophobic formulations and greater stability in moisture-sensitive systems.
Q3: Is TEGOAMIN B 75 suitable for low-emission or automotive interior applications?
A: Yes — due to its relatively low volatility and favorable emission profile, TEGOAMIN B 75 is frequently selected for formulations targeting reduced fogging and VOC emissions, including automotive foam and interior coating systems where regulatory and performance requirements are stringent.
Q4: What is the typical dosage range for TEGOAMIN B 75 in PU foam formulations?
A: Dosage is formulation-dependent, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the total polyol component — to achieve desired cure kinetics without compromising foam stability or final properties.
