電気通信用屋外施設等への広範な応用が可能である。The object of the present invention is to achieve a molecular weight of 50.
A low molecular weight tetrafluoroethylene resin powder fluorinated from 0 to 20,000 and terminated to an acrylic silicon resin, a polyester resin, an epoxy resin, an acrylic resin, a urethane resin, a fluororesin, or at least one resin or a mixed resin. A water-repellent paint characterized by being mixed and dispersed so as to have a volume fraction of 1 to 70% by volume after volatilization of volatile components, and a coating method using the paint. Can be achieved. Above "Molecular weight is 500
Low molecular weight tetrafluoride fluorinated up to 20,000 and terminated
Of the "Volume fraction of volatile resin components after volatilization of volatile components"
As a method, for example, a scanning type of
The low molecular weight ethylene tetrafluoride resin powder
Is measured, and this area fraction is directly used as a volume fraction.
There is a method. A detailed explanation of this method can be found in the examples
In example, DeHoff et al., Kunio other translation Makishima "Weighing morphology" Uchida Rotsuru
Fields, 1972, pages 51-87. The application range of this paint is wide, and for example, it can be widely applied to outdoor facilities for telecommunications that require long-term reliability.

る。Further, by attaching an acrylic silicone resin or the like to the object to be coated prior to the application of the paint, the corrosion resistance can be further enhanced. Also, after the acrylic silicon resin or the like is adhered to the object to be coated, before the volatile components are completely volatilized, a low molecular weight tetrafluoroethylene resin powder having a molecular weight of 500 to 20,000 and fluorinated to the terminal is applied to the surface area. By adhering so that the fraction is 1 to 70%, effects such as water repellency can be concentrated on the surface.

性の効果が現れず、70％以上では四弗化エチレン樹脂が
上記樹脂から脱離することによる。In the above, the molecular weight of the ethylene tetrafluoride resin is
If the molecular weight is less than 500, it is difficult to produce tetrafluoroethylene resin economically because the molecular weight is less than 500.Moreover, if the molecular weight is more than 20,000, it is difficult to completely fluorinate the carbon bond. This is because the water repellency decreases.
In addition, the fluorination to the terminal is for preventing a bond and a hydrogen bond due to an electric polarity with a water molecule which is a factor of inhibiting properties such as water repellency. Also, tetrafluoroethylene
The reason why the fraction of the resin is set to 1 to 70% is that the water repellency effect does not appear at 1% or less, and the ethylene tetrafluoride resin is desorbed from the resin at 70% or more.
