Standard Test Method for Pressure Mottling and Blocking Resistance of Organic Coatings on Metal Substrates
|Publication Date:||10 June 2001|
|ICS Code (Organic coatings):||25.220.60|
This test method covers determination of the pressure mottling and sticking, or blocking resistance of organic coatings applied to coil-coated or factory-coated metal prior to fabrication.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
Definitions of Terms Specific to This Standard:
blocking or sticking, n-the condition wherein coated surfaces adhere to each other.
pressure mottling, n-film distortion or uneven pattern giving a change of gloss and nonuniform appearance. It is usually caused by pressures within a painted coil or stacked painted sheets or other painted products.
