PURPOSE: A hydrophilic coating composition is proposed to control bad smell or odor from heat exchanger due to its low ability to adsorb and/or desorb the odor components by means of the hydrophilic resin coating. CONSTITUTION: A hydrophilic resin coating is produced by applying or spreading ethyleneoxide compounds and a polymer selected from phenol or bisphenol frameworks and dissolved in water on any subject and drying it. Alternatively, the hydrophilic resin coating can be prepared by applying or spreading the polymer selected from phenol or bisphenol frameworks and dissolved in ethyleneoxide solution in water on the subject and drying it. The ethyleneoxide compound has epoxy radicals and is selected from sorbitol, polyglycerol, pentaerythritol, diglycerol, glycerol and so on. |
