Q1: What is the primary function of EPIKOTE WD-510 in waterborne epoxy systems?
A: EPIKOTE WD-510 is a low-viscosity, water-dispersible epoxy resin designed to serve as the base resin component in two-component waterborne epoxy coatings and adhesives. It enables stable emulsion formation with compatible amine hardeners and contributes to film formation, chemical resistance, and mechanical performance after cure.
Q2: How is EPIKOTE WD-510 typically formulated with hardeners?
A: WD-510 is generally paired with waterborne polyamine hardeners—such as modified aliphatic or cycloaliphatic amines—that are specifically designed for compatibility and reactivity in aqueous dispersions. Formulation requires careful pH control, mixing sequence, and adjustment of solids content to ensure stability and optimal pot life.
Q3: Can EPIKOTE WD-510 be used in food-contact or industrial maintenance applications?
A: EPIKOTE WD-510 is intended for industrial protective coatings and high-performance maintenance systems where waterborne technology is preferred. While it meets general requirements for low VOC and reduced solvent use, suitability for regulated food-contact applications depends on full system formulation, curing conditions, and compliance verification by the end-user under applicable regional regulations.
Q4: What are key handling and storage considerations for this product?
A: Store EPIKOTE WD-510 in tightly sealed containers at temperatures between 10°C and 30°C, away from freezing and excessive heat. Avoid prolonged exposure to humidity or contamination during handling. Prior to use, inspect for phase separation or viscosity changes—gentle stirring may be required if settled, but do not use if gelling or significant coagulation is observed.
