FIELD: physics.
SUBSTANCE: method for determining the adhesive strength of paint coatings is disclosed, including sample preparation, testing, obtaining and analyzing the results. In preparation for testing, the free edge of the substrate is placed in the clamping mechanism and fixed with a sleeve through the hole in the clamping mechanism and the substrate. When carrying out tests, the substrate is torn off from the cell with a paint and varnish coating, control of the separation of the substrate perpendicular to the base is carried out by laser levels.
EFFECT: ensuring an increase in accuracy and a decrease in labor intensity in determining the adhesive strength of paint coatings.
