Determination of Adhesion of Paint Film

The adhesion of paint film is determined by assessing the bonding strength between the coating and the substrate through methods such as the cross-cut test or pull-off test. The cross-cut test involves using a cutting tool to create a grid pattern and observing the extent of paint film detachment. The pull-off test uses an adhesive to connect test studs and quantitatively measures the force required for separation. These methods are used to evaluate the reliability of coating adhesion on surfaces such as walls, metals, and plastics.
Selection
When selecting, consider the hardness of the substrate: use the cross-cut method for hard substrates and the pull-off method for soft substrates. The testing standards refer to national standards or ASTM, with laboratory environmental conditions controlled for temperature and humidity. Instrument selection should match the coating thickness: choose a cross-cut tester for thin coatings and a tensile tester for thick coatings. Portable equipment is prioritized for on-site testing.
