Functions of Surface Treatments
Pretreatments and functional coatings endow automotive and general industrial products,
steel, beverage cans, and various other materials with functions.
Functional Agents
Hydrophilic treatments
We have two types of hydrophilic coatings for heat exchangers: the pre-coating type for treating the aluminum plate for heat exchangers and the post-coating type for treating the heat exchanger itself. Hydrophilic coatings prevent bridges of condensate between the fins by making the surface of the heat exchanger hydrophilic, which prevents the reduction of cooling efficiency. The special resin provides good hydrophilicity and reduces odor from the evaporator with its low-adsorption property. Rust prevention can be improved by using it with primer. We will consider improved products with your input.
