Q1: What is the primary function of ShiftMax 210 in polyurethane production?
A: ShiftMax 210 is a high-performance, non-tin catalyst specifically designed to promote the urethane reaction (isocyanate–polyol coupling) while offering excellent selectivity and reduced side reactions such as trimerization or hydrolysis. It enables robust processing control and improved foam cell structure in flexible and semi-rigid PU foams.
Q2: Is ShiftMax 210 compatible with other catalysts commonly used in PU systems?
A: Yes — ShiftMax 210 is formulated for broad compatibility with amine-based catalysts (e.g., DABCO® variants) and other metal-free or low-metal catalysts. It can be effectively balanced in co-catalyst systems to fine-tune cream, rise, and cure profiles without compromising storage stability of formulated premixes.
Q3: How should ShiftMax 210 be handled and stored to maintain performance?
A: ShiftMax 210 should be stored in its original sealed container under dry, cool conditions (typically below 30 °C), protected from moisture and direct sunlight. It is hygroscopic and may undergo gradual degradation upon prolonged exposure to humid air; therefore, containers should be resealed promptly after use.
Q4: Does ShiftMax 210 contain heavy metals or restricted substances?
A: No — ShiftMax 210 is a tin-free, heavy-metal-free catalyst developed in alignment with evolving regulatory expectations and sustainability goals. It contains no lead, mercury, cadmium, hexavalent chromium, or organotin compounds, supporting compliance with major industry stewardship initiatives.
