Abstract

The views of Dr. Harvest L. Collier on preventing skinning and evaluating corrosion protection of additives for waterbornes are discussed. The alkyd resins, while in contact with air reactively crosslink to form films resistant to attack by water and other air pollutants. The anti-skinning agents function through two mechanisms and either scavenge the oxygen radicals that are formed near the surface or reduce the latent concentration of metal drier ions. It is observed that corrosion-inhibiting additives drastically modify the adhesion water uptake blistering behavior and substrate protection of water-borne coatings.
