Epoxy Primer · Paint & Coating Systems
PPG / Sigma Coatings Sigma Primer Mast/Derrick is a Epoxy Primer within the Paint & Coating Systems category. It is typically installed on the designated hull, deck, tank, machinery-space or topside substrate as part of the vessel’s protective coating system. Its engineering role is to protect steel or other substrates from corrosion, fouling, wear or environmental exposure according to the coating type. The complete model designation should be retained when matching drawings, certificates, service information and spare parts because neighboring variants may differ in configuration even when they share the same equipment family. The exact shipboard arrangement and interfaces remain installation-specific and should be checked against the vessel’s approved drawings and equipment documentation.
