Abstract

Decreasing the permeability of water and oxygen is important to inhibit the corrosion behavior of metals. The permeation behavior of gas, vapor and liquid to polymer film is discussed and the effect of polymer type and pigment on the barrier properties is analyzed. The permeability is related with diffusivity and solubility. The decrease of permeability of oxygen and water could improve the anticorrosion performance of coatings.
