... are semipermeable membranes. Water-soluble impurities commonly exist at the coating-substrate interface (e.g., salt residues from pretreatment processes, hard water salts, etc.). These impurities can lead to osmotic blistering. That is, water permeates through the paint film to achieve equilibrium...

Baking, or heating of tank interior coatings, is often done both to ensure solvent evaporation from the paint film and to elevate...

Many ballast tanks can be complex in nature ( Fig. 3 , 4 ) compared to large, single compartments, providing challenges for proper ventilation. Improperly vented tanks lead to solvent entrapment, an improperly cured film, osmotic blistering...
