Laboratory opacity testing plate

Laboratory opacity test panels are used to measure the hiding power of coatings. The principle involves evenly applying the coating onto a black-and-white checkerboard surface and evaluating the hiding performance by observing the extent to which the black and white squares are covered. Its purpose is to provide reference for adjusting coating formulations and determining application thickness. It is applied in quality control during coating production, research and development comparisons, and construction guidance.
Selection
When selecting an opacity test panels, consider the substrate material: metal panels are durable, while paper panels are economical. The black and white grid areas should have clear boundaries and distinct contrast. The size should match the width of commonly used applicators. Surface flatness affects the accuracy of the test. Ease of cleaning after use should also be considered.
