Case Study: E.H. Hassell & Sons
Traditional Marine Specification Productivity limitations and QC issues
Kortec have been supplying protective coatings to E.H. Hassell & Sons Ltd since 2007. We upgraded their system a number of times through to 2011 as their client increased their coating service life expectations — finally requesting “in excess of 15 years in a marine environment” (ISO12944 C5M-High). This was achieved using a traditional marine specification at the client’s request, involving a two-pack epoxy zinc rich primer, plus a two-pack epoxy zinc phosphate midcoat, followed by a two-pack polyurethane topcoat. This system had a total Dry Film Thickness (DFT) of 330 microns.
