When working with anti-corrosion coatings, MEK resistance is a critical indicator of the quality and durability of your primers. ASTM D4752-20 defines a standardized test method for evaluating the methyl ethyl ketone resistance of inorganic zinc-rich ethyl silicate primers using a controlled solvent rub technique. This test simulates mechanical stresses and chemical exposures that coatings are subjected to in practice. The importance of this test…
