Q1: What is the primary function of BECKOPOX EH 2189w 50WA in epoxy systems?
A: BECKOPOX EH 2189w 50WA is a water-dispersible aliphatic amine curing agent designed to provide efficient ambient- or low-temperature cure of epoxy resins, delivering good chemical resistance, mechanical strength, and low viscosity for easy incorporation into aqueous or solvent-reduced formulations.
Q2: Is this product suitable for high-solids or waterborne epoxy coatings?
A: Yes — EH 2189w 50WA is specifically formulated as a water-dispersible amine, making it well-suited for waterborne epoxy coating systems and compatible with high-solids epoxy formulations where reduced VOC content and improved handling safety are priorities.
Q3: How does the “50WA” designation relate to its formulation and performance?
A: The “50WA” indicates a water-based dispersion containing approximately 50% active amine solids. This format enhances stability in aqueous systems, reduces handling hazards associated with neat amines, and supports consistent metering and mixing in industrial production environments.
Q4: Can BECKOPOX EH 2189w 50WA be used in food-contact or protective lining applications?
A: While EH 2189w 50WA is designed for industrial protective coatings and general-purpose epoxy curing, suitability for food-contact applications depends on full system formulation, final cure conditions, and compliance verification by the end-user against applicable regulatory frameworks — Allnex does not pre-certify finished systems for such uses.
