Analysing customized coatings’ solutions is essential to hinder the corrosion under insulation (CUI) phenomenon. In this article Simon Daly explains how Hempel, one of the corrosion protection coatings world leaders, supports the applicators to overcome this issue.

This severe and particularly disruptive form of corrosion occurs

on insulated carbon and low alloy steel as well as stainless-steel
