Q1: What is the primary function of EPIKOTE 3522-W-60A in waterborne coating systems?
A: EPIKOTE 3522-W-60A is a self-emulsifying, waterborne epoxy resin designed to serve as a reactive binder or co-resin in high-performance, low-VOC industrial and protective coatings. It contributes adhesion, chemical resistance, and crosslink density when paired with compatible waterborne curing agents.
Q2: Can EPIKOTE 3522-W-60A be used without organic co-solvents?
A: Yes — it is formulated for stable dispersion in water and typically requires minimal or no added organic co-solvents to achieve viscosity control or film formation, supporting compliance with stringent VOC regulations in architectural and industrial applications.
Q3: Which types of curing agents are compatible with this resin?
A: It is commonly paired with water-dispersible polyamine hardeners, including aliphatic and cycloaliphatic amine adducts. Compatibility should be confirmed through formulation testing, as performance depends on pH, mixing sequence, and ambient cure conditions.
Q4: How does EPIKOTE 3522-W-60A differ from solvent-based epoxy resins in terms of application handling?
A: Unlike solvent-based counterparts, it offers reduced odor, lower flammability risk, and simplified ventilation requirements during application. It also enables ambient-temperature cure in many formulations, though drying and final property development may be more sensitive to humidity and substrate moisture content.
Q5: Is EPIKOTE 3522-W-60A suitable for food-contact or potable water applications?
A: It is not pre-approved for direct food-contact or potable water applications. Formulators must conduct full regulatory evaluation—including migration testing and compliance verification—against applicable regional requirements before use in such end uses.
