Significance and Use | ||||||||||||||||||||
Water-blast cleaning with, (SSPC-TR2/NACE 6C 198) or without, (SSPC-SP 12/NACE No. 5) abrasive, results in flash rusting under some environmental conditions. Inhibitors are used to prevent flash rusting while drying and before coating application. The inhibitor or reaction products of the inhibitor on the substrate becomes part of the coating systems. Coating performance may be influenced by the inhibitor. Soluble contaminants or unreacted inhibitors left on the surface under the coating may cause premature failure. This practice includes a comparison of coating performance with and without inhibitors using various laboratory tests to simulate a range of conditions such as high moisture, marine atmospheric or water immersion. The user or specifier must determine the specific test methods to be used and exposure conditions. Some test methods referenced may not be applicable to all types of coatings. |

1. Scope | ||||||||||||||||||||
1.1 This practice covers procedures to evaluate the compatibility of coatings with inhibitors used to prevent flash rusting of steel before application of coatings. 1.2 The inhibitors are used with water-blast cleaning surface preparation and may be used with or without abrasives. 1.3 The manufacturer of the coatings shall be consulted to ensure compatibility of inhibitors with the coatings. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. |
