DOW DER WB3002 Waterborne Epoxy Resin – Frequently Asked Questions (FAQ)
Q1: What are the primary advantages of using DOW DER WB3002 compared to solvent-based epoxy resins?
A: DOW DER WB3002 offers significantly reduced VOC content, improved workplace safety, and simplified handling due to its waterborne nature. It enables formulators to meet increasingly stringent environmental regulations while maintaining good film formation, adhesion, and chemical resistance in cured coatings.
Q2: Can DOW DER WB3002 be used in ambient-cure applications, or does it require elevated temperature curing?
A: DOW DER WB3002 is designed for ambient-temperature cure when paired with compatible waterborne amine hardeners. Full property development typically occurs over several days at room temperature, though performance can be accelerated with mild thermal post-cure if process conditions allow.
Q3: Is DOW DER WB3002 compatible with common waterborne acrylic or polyurethane dispersions?
A: Yes — DOW DER WB3002 exhibits good compatibility with many commercially available waterborne acrylics and anionic polyurethane dispersions, enabling hybrid formulations that balance epoxy functionality with flexibility, UV stability, or cost-efficiency. Compatibility should always be verified experimentally in the final formulation.
Q4: How does freeze-thaw stability affect storage and handling of DOW DER WB3002?
A: DOW DER WB3002 is not inherently freeze-thaw stable. Prolonged exposure to sub-zero temperatures may cause irreversible coagulation or viscosity changes. It should be stored above 5°C (41°F) in tightly sealed containers, and frozen material should not be used without thorough evaluation of performance properties.
