Q1: What is the primary function of EPIKOTE WD-512 in waterborne coating systems?
A: EPIKOTE WD-512 serves as a reactive waterborne epoxy resin component, primarily used to enhance crosslink density, chemical resistance, and adhesion—especially on metal and concrete substrates—within low-VOC, two-component waterborne epoxy coatings.
Q2: How does EPIKOTE WD-512 differ from solvent-based epoxy resins in formulation handling?
A: Unlike solvent-based counterparts, WD-512 is supplied as a stable aqueous dispersion, eliminating the need for organic solvents during initial incorporation. It exhibits good compatibility with common waterborne amine hardeners and allows for lower VOC formulations without sacrificing film integrity or pot life under standard mixing conditions.
Q3: Can EPIKOTE WD-512 be used in food-contact or hygiene-critical applications?
A: EPIKOTE WD-512 is not pre-certified for direct food contact. Its suitability for hygiene-sensitive environments (e.g., pharmaceutical or dairy facilities) depends on full system validation—including hardener selection, cure conditions, and end-use regulatory review—by the coating formulator and end-user.
Q4: What are key storage and handling recommendations for this product?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from freezing and prolonged exposure to high heat or direct sunlight. Avoid contamination with incompatible materials (e.g., strong acids or oxidizers), and ensure thorough mixing before use if phase separation is observed after extended static storage.
