Abstract
Overall migration through epoxy layer coated wood was investigated to estimate the coating thickness satisfying the regulatory limit. As an index of overall migration, KMnO$_4$ oxidizable extractives by the food simulant water solution was used. Migration pattern in interest range could described by a simple diffusion model and the temperature dependence of the permeability index could be explained by Arrhenius equation. The thickness of epoxy coating greater than 0.004 mm was analyzed to be required for satisfying the regulatory guideline.
