Q1: What is the primary function of EPIKOTE 3515-W-60A in waterborne coating systems?
A: EPIKOTE 3515-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 coatings—particularly where corrosion resistance, adhesion to metal substrates, and compatibility with amine-based curing agents are required.
Q2: Can EPIKOTE 3515-W-60A be used without a separate curing agent?
A: No—it is not a standalone coating. This product is a base resin that requires blending with a compatible waterborne amine hardener (e.g., Hexion’s ANCAMINE® or similar aliphatic polyamine dispersions) to achieve full crosslinking and optimal film properties.
Q3: How does EPIKOTE 3515-W-60A differ from solventborne epoxy resins in terms of application handling?
A: As a waterborne system, it offers reduced odor, lower flammability risk, and simplified regulatory compliance for VOC-sensitive environments. It typically requires careful attention to ambient humidity and substrate temperature during application to ensure proper coalescence and film formation—unlike solventborne counterparts, which rely more on solvent evaporation kinetics.
Q4: Is EPIKOTE 3515-W-60A suitable for food-contact or potable water applications?
A: This resin is not pre-approved for direct food-contact or potable water applications. Formulators must conduct full regulatory evaluation—including end-use testing and compliance verification with relevant national or regional frameworks—before considering such use.
