- Abstract
- At the request of the U. S. Army Natick Research, Development and Engineering Center, a practical method was developed for measuring the adhesion of paints applied to shelters. As recommended in the Phase 1 report, a pull-off test based on the use of a commercially available pneumatic testing device was chosen. The procedure includes ways of controlling the substrate stiffness, a parameter that affects the test results, and a process for obtaining acceptable levels of adhesion for a particular substrate. The estimated precision (standard deviation) of the method is 9 percent. In a pilot study to determine the extent to which small differences in surface preparation would affect differences in pull-off test results, it was found that, at least for aluminum, the procedure was insensitive to small differences in surface preparation.
