Abrasion Resistant Overcoating (ARO) is a hard, mechanically strong top coating for all fusion-bonded epoxy pipeline corrosion protection coatings. When applied at great thickness, is also enhances the hot, wet performance of the first layer of corrosion coating. It is applied to the base coating to form a tough outer layer that is resistant to gouge, impact, abrasion and penetration.

This coating is specifically designed to protect the primary corrosion coating from damage during pipeline directional drilling applications, bores, river crossing, and installation in rough terrain. It is a thermosetting, integrally bonded to the base coating and does not shield from cathodic protection. Excellent flexibility provides an added service advantage over other top coating systems. ¹ This type of coating is also known as FBE Dual Coating.
