In paint application, the thickness of the paint is extremely thin at the edges compared to the flat areas. This edge coating is called edge coverage.
Since the performance of paint is proportional to the thickness of the paint film, the original performance will not be achieved in extremely thin areas, resulting in cracks and other defects.
Therefore, it is important to ensure the coating thickness not only on the flat areas but also on the edges to maintain the performance of the coated object.
The ability to thicken the edge of a coating is an important factor in the performance of a coating, and this performance is referred to as edge coverage.
