Q1: What is the primary application advantage of EPIKOTE 5520-W-60A compared to solvent-based epoxy resins?
A: EPIKOTE 5520-W-60A offers significantly reduced VOC content and improved workplace safety due to its waterborne formulation, while maintaining good film formation, adhesion to metallic and concrete substrates, and compatibility with common amine-based curing agents for protective coatings.
Q2: Can this resin be used in high-humidity or low-temperature curing conditions?
A: Yes — as a waterborne system, EPIKOTE 5520-W-60A demonstrates improved tolerance to ambient humidity during application and film formation compared to many conventional epoxies. It also supports cure at temperatures as low as 10°C when paired with appropriately selected water-dispersible hardeners, though full performance development may require extended ambient post-cure time.
Q3: How should EPIKOTE 5520-W-60A be stored and handled to maintain stability?
A: Store in original, tightly sealed containers at temperatures between 5°C and 30°C, away from freezing and direct sunlight. Avoid prolonged exposure to high shear mixing or excessive dilution with deionized water beyond manufacturer-recommended levels, as these may compromise colloidal stability and shelf life.
Q4: Is EPIKOTE 5520-W-60A compatible with common pigment dispersions and additives used in waterborne coatings?
A: Yes — it is generally compatible with anionic and nonionic surfactant-stabilized pigment preparations, rheology modifiers, defoamers, and coalescing agents designed for aqueous epoxy systems. Compatibility testing under actual formulation conditions is recommended to ensure colloidal stability and final film integrity.
