Q1: What is the primary function of the ISOXYL EBI Series catalyst in polymer processing?
A: The ISOXYL EBI Series is a highly efficient epoxy-based catalyst designed to promote crosslinking and cure reactions—particularly in thermosetting resins, coatings, and adhesives—enabling faster gel times, improved network formation, and enhanced thermal and mechanical performance.
Q2: Is the ISOXYL EBI Series compatible with common epoxy resin systems?
A: Yes, it demonstrates broad compatibility with standard bisphenol-A and bisphenol-F epoxies, as well as novolac-type resins. Compatibility with specialty or modified epoxies should be verified through small-scale formulation testing under intended process conditions.
Q3: How should the catalyst be incorporated into a formulation?
A: It is typically added during the late-stage mixing phase under controlled temperature and moisture-free conditions to ensure uniform dispersion and avoid premature reactivity. Pre-dilution in a compatible solvent or resin portion may be recommended for optimal handling and distribution.
Q4: What storage conditions are recommended to maintain catalyst stability?
A: Store in original sealed containers at temperatures between 5 °C and 25 °C, protected from moisture, direct sunlight, and strong oxidizing agents. Prolonged exposure to elevated temperatures or humidity may reduce catalytic activity over time.
