Two-component epoxy paint

A two-component epoxy paint cures by chemical reaction between an epoxy resin base and a separate amine or polyamide hardener mixed at a fixed ratio, not by solvent evaporation, giving a hard chemically resistant film. It is the standard ballast-tank and immersion coating under the IMO Performance Standard for Protective Coatings (PSPC, resolution MSC.215(82)), which requires a light-colored, hard, epoxy-based system with a nominal dry film thickness of 320 microns applied in two coats plus stripe coats at edges and welds, over an Sa 2.5 blast. PSPC enforces the 90/10 rule: at least 90% of DFT readings at or above 320 microns, the remaining readings not below 288 microns (0.9 times NDFT).
