Method can enumerate dipping, spraying, hairbrush coating, rod coaters, curtain coating etc..In addition, coating composition is coated on substrate
Surface after, remaining coating composition can be removed with air-flow.Remaining coating composition substrate surface detention
In the case of, the film thickness for being formed by film in this section thickens, and cracks in film sometimes or film gonorrhoea.In turn,
Remaining coating composition dry flower is time-consuming, and do not obtain anti-pollution fully sometimes, therefore not preferably.For
For the method remaining coating composition removed with air-flow, dry facilitation effect caused by air-flow is also obtained, it may have
The advantages of good film easy to form.
Preferably 100 DEG C of the temperature of air-flow hereinafter, more preferable 60 DEG C or less.If the temperature of air-flow is excessively high, sometimes acrylic acid
It is that resin, fluororesin be rotten and the reduced performance of film.On the other hand, if the temperature of air-flow is 25 DEG C hereinafter, drying sometimes
Time is elongated without preferred.Temperature of the Time Dependent of jet-stream wind in air-flow, substrate shapes, therefore be not particularly limited, such as
Fruit is the substrate of simple shape, preferably 2 seconds or more and 20 seconds or less.If it is multiple with having as small gap, hole
The substrate of miscellaneous shape, the time of jet-stream wind preferably 5 seconds or more and 50 seconds or less.If the time of jet-stream wind is too short, have
When remaining coating composition residual.On the other hand, it if the overlong time of jet-stream wind, does not obtain fully sometimes antifouling
Performance.
It is preferably purple by being irradiated to dry coating in the case where acrylic resin is UV curing type acrylic resin
Outside line makes curing of coating.Exposure intensity is preferably 30W/cm2Above and 300W/cm2Hereinafter, irradiation time be preferably 3 minutes with
It is upper and 10 minutes or less.If exposure intensity is less than 30W/cm2, curing reaction is not sufficiently carried out sometimes.On the other hand, such as
Fruit exposure intensity is more than 300W/cm2, xanthochromia is cracked or occurred in film sometimes.In addition, if irradiation time less than
3 minutes, curing reaction was not sufficiently carried out sometimes.On the other hand, if irradiation time is more than 10 minutes, sometimes in film
It cracks, defect.
The case where acrylic resin is a solution curing type acrylic resin or two-solution curing type acrylic resin
Under, preferably make curing of coating by the way that dry coating is heated 30 minutes or more at 100 DEG C or less, preferably 60 DEG C or less.
The film thickness that film is formed by substrate is preferably 0.1 μm or more and 10 μm or less.If the film thickness of film is not
To 0.1 μm, anti-pollution is not obtained fully sometimes.On the other hand, if the film thickness of film is more than 10 μm, sometimes in film
In crack.
As substrate, it is able to use the portion for requiring the various products of anti-pollution, wear resistance, the transparency and high waterproofness
Part.As the example of such component, heat exchanger, fan, impeller, the wing flap (Off ラ ッ プ), wind path of air conditioner can be enumerated
Form component, cover etc..In addition, the material as substrate, such as polypropylene, polystyrene, ABS resin, ASG resin can be enumerated
Metals, the glass such as equal plastics, stainless steel, aluminium etc..
