Q1: What is the primary function of TMG 315 in polyurethane systems?
A: TMG 315 is a tertiary amine-based catalyst designed to promote the urethane reaction (isocyanate–polyol coupling), offering balanced reactivity and improved flow characteristics—particularly beneficial in flexible slabstock and molded foam applications.
Q2: Is TMG 315 compatible with water-blown and low-emission PU formulations?
A: Yes, TMG 315 exhibits good compatibility with water-blown systems and supports low-VOC and low-amine-odor formulations when used as part of a carefully balanced catalyst package.
Q3: How does TMG 315 compare to traditional triethylenediamine (DABCO® 33-LV) in processing behavior?
A: TMG 315 delivers comparable gelling activity but with reduced volatility and milder odor profile, contributing to improved workplace handling and enhanced stability in premixes over extended storage periods.
Q4: Can TMG 315 be used in combination with other catalysts?
A: Yes—it is commonly blended with delayed-action catalysts or surfactants to fine-tune cream time, rise profile, and cell structure; compatibility should be verified empirically for each specific formulation.
Q5: What are the recommended storage conditions for TMG 315?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from moisture, direct sunlight, and strong oxidizing agents to maintain catalytic performance and shelf life.
