ASTM D5402 PDF

These coatings should reach specific levels of solvent resistance prior to being topcoated and prior to placing in service; the levels of solvent resistance necessary vary with the type of coating and the intended service. Rubbing with a cloth saturated with the appropriate solvent is one way to determine when a specific level of solvent resistance is reached. However, the level of solvent resistance by itself does not indicate full cure and some coatings become solvent resistant before they become sufficiently cured for service. The coating manufacturer may specify the solvent, the number of double rubs, and the specific test results needed.

ASTM D5402-93- Assessing Solvent Resistance of Coatings Using Solvent Rub.

The MEK resistance of some IOZ primers has been shown to correlate well with the cure of the primer as determined by diffuse reflectance infrared spectroscopy. As we know, the ethyl silicate cures by the reaction of the vehicle with moisture to provide the complete binder matrix. Curing is a function of the amount of available relative humidity and temperature. A certain level of cure is necessary for the IOZ primer to support a topcoat. The cure rating required for the application of specific topcoats must be agreed upon before the test method is used.
