Abstract / scope
Assessing by means of a simple method, the resistance of a coating film to imprinting by a nylon gauze under a specified force applied for a specified time. The method may be carried out either as test by determining whether the print-free state has been reached after a specified period of drying or, in the case od stoving coatings, after stoving and ageing under specified conditions, or by repeating the print-free test at suitable intervals.
