Adhesion durability of polyethylene/adhesive polyethylene coated steel with and without epoxy primer in distiled water at 25~80℃ were investigated Temperature dependence of time to 20, 50, 100 Ncm-1 for 90 ° peel strength after immersion test shows Arrenius equation. The apparentactivation energy from the Arrenius equation is the almost same as that of diffusion coefficient for water through polyethylene coating. The adhesion durability at the lower temperature is predicted by using Arrenius equation.
