What the significance of adhesion testing in paints and coatings?What are the different test methods for adhesion testing? Good adhesion is critical to the integrity and long-term performance of a coating. Poor adhesion can result in failure, corrosion and contamination of surfaces or contents. So, it’s vitally important to undertake adhesion testing to assess the quality of the attachment between the dry paint film (coating) and its substrate. Test Methods: Pull-off Test — This procedure is accomplished by sticking a loading fixture perpendicularly to the coating, then slowly increasing tensile load until either the fixture and adhesive layers are removed or … Continue reading What is adhesion test
