Modern water-based epoxy primers have closed the performance gap with solvent-based systems. Lab testing shows: salt spray resistance within 10%, adhesion equivalent, hardness within 1H pencil grade, and flexibility comparable. The main difference is cure time (water-based slightly longer) and minimum application temperature (above 10°C vs 5°C). For most industrial applications, water-based now offers equivalent protection with major environmental benefits.
