Ensuring the durability and effectiveness of anti-rust coatings on urban outdoor metal furniture requires rigorous adhesion testing. Various methods are employed to evaluate how well the coating bonds to the metal substrate, which is crucial for long-term performance in harsh environmental conditions. Common adhesion test methods include the cross-cut test, where a grid pattern is scored into the coating and assessed for flaking; the pull-off test, which measures the force required to detach the coating; and the scrape adhesion test, evaluating resistance to mechanical damage. These tests help manufacturers and maintenance teams verify coating integrity, prevent premature failure, and ensure furniture remains protected against corrosion, extending its lifespan in public spaces.
