Measuring MEK Resistance of Ethyl Silicate (Inorganic) Zinc-Rich Primers by Solvent Rub1. ness of Protective Coating Systems by Destructive Means5 D Practice for Assessing the Solvent Resistance of Organic Coatings Using Solvent Rubs5 3. the methyl ethyl ketone (MEK) rub. MEK Solvent Rub Resistance test (ASTM D) where a value of 4 indicates a satisfactory degree of cure for overcoating purposes. Note.

The MEK resistance of some two-component ethyl silicate zinc-rich primers has been shown to correlate well with the cure of the primer as determined by diffuse reflectance infrared spectroscopy. The technique can be used in the laboratory, field, or in the fabricating shop. Practice D is the preferred method for organic coatings. The values given in parentheses are for information only. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Rate the results in accordance with Table 1.

See Appendix X1 Goodness. Keywords 9. Using the procedure outlines in this test method, eight different operators were asked to rate, in triplicate, the methyl ethyl ketone MEK rub resistance of a particular inorganic zinc-rich primer. The primer was separately applied to multiple test panels at two different dry lm thickness ranges; 2. Separate test panels corresponding to each coating thickness category were scored after a 6-h cure period and a h cure period.

Performance ratings and general statistical information have been in Table X1.
