Standard Test Method for Sag Resistance of Paints Using a Multinotch Applicator

Importancia y uso:

4.1 Evaluation of sag resistance is essential in quality control for both producers and purchasers of coatings. Practical application tests are poor in reproducibility, while viscometric methods, for example Test Methods D2196, are time-consuming and lack the convincing aspect of actual sagging. This method provides simple and rapid tests, whereby sag resistance is demonstrated by a visible sag pattern, and is rated objectively in terms of numerical values that correlate with brushout test observations.
