Evaporator surface treatment technology is important for air conditioners in that it provides resistance to rust, odor and bacteria, while imparting hydrophilicity. However, since the first-layer chromate coating contains hexavalent chromium, an environmental loading substance whose stricter regulation is under consideration, development of an alternative technology is needed. We selected titanium coating for the first-layer non-chromate coating, and added an inhibitor to the second-layer multifunctional resin coating to impart a self-healing effect without undermining the other functions. As a result, we succeeded in developing a non-chromate surface technology that ensures the same level of rust resistance and other qualities as with conventional technology.
