Q1: What is the primary function of Umicore ECOS ND 15 Catalyst in polyurethane systems?
A: Umicore ECOS ND 15 is a non-tin, metal-free catalyst designed to promote the urethane reaction (isocyanate–polyol coupling) with high selectivity and reduced side reactions, supporting improved pot life control and enhanced foam or elastomer morphology.
Q2: Is ECOS ND 15 suitable for use in low-VOC or bio-based polyurethane formulations?
A: Yes — as a non-metallic, amine-based catalyst, ECOS ND 15 contributes to lower heavy metal content and aligns well with VOC-reduction strategies and formulations incorporating renewable polyols, without compromising catalytic efficiency.
Q3: How does ECOS ND 15 compare to traditional tin catalysts in terms of hydrolytic stability?
A: Unlike stannous octoate, ECOS ND 15 exhibits significantly improved resistance to hydrolysis, making it more robust in moisture-sensitive applications and extending shelf life in pre-mixes containing reactive components or trace water.
Q4: What are typical handling and storage recommendations for ECOS ND 15?
A: Store in tightly sealed original containers under dry, cool conditions (below 30 °C), protected from moisture and direct sunlight. Avoid prolonged exposure to ambient humidity during handling to maintain catalytic consistency and shelf life.
