することによる。[Function] In the above, the molecular weight of tetrafluoroethylene is 500
The range of up to 20000 is because it is difficult to produce ethylene tetrafluoride economically with a molecular weight of 500 or less, and it is difficult to completely fluorinate the carbon bond with a molecular weight of 20000 or more. , Because the water repellency is reduced. Further, the reason for fluorinating to the terminal is to prevent a bond and a hydrogen bond due to electric polarity with a water molecule, which becomes a factor for inhibiting properties such as water repellency. Further, the reason why the tetrafluoroethylene fraction is set to 1 to 70% is that the effect of water repellency does not appear at 1% or less, and the tetrafluoroethylene is desorbed from the above resin at 70% or more.

１〜70％としたのは、１％以下でははっ水性の効果が現
れず、70％以上では四弗化エチレンが上記樹脂から脱離
することによる。[Function] In the above, the molecular weight of tetrafluoroethylene is 500
The range of up to 20000 is because it is difficult to produce ethylene tetrafluoride economically with a molecular weight of 500 or less, and it is difficult to completely fluorinate the carbon bond with a molecular weight of 20000 or more. , Because the water repellency is reduced. Further, the reason for fluorinating to the terminal is to prevent a bond and a hydrogen bond due to electric polarity with a water molecule, which becomes a factor for inhibiting properties such as water repellency. Further, the reason why the tetrafluoroethylene fraction is set to 1 to 70% is that the effect of water repellency does not appear at 1% or less, and the tetrafluoroethylene is desorbed from the above resin at 70% or more.

有していることが明らかとなった。When a contact angle was measured by dropping a water drop on this sample, a value of 110 degrees was obtained, showing excellent water repellency.
Then, the contact angle of this sample was measured after irradiating it with ultraviolet rays for 600 hours (corresponding to outdoor exposure for 3 years) using a sunshine weather meter, and it showed a value of 107 degrees, which was known to have excellent weather resistance. Since this sample has water repellency, it is possible in principle to avoid corrosion, snow accretion, etc. that occur due to the adhesion of water. Furthermore, when the surface of this sample was rubbed with No. 600 emery paper, it was revealed that the sample had lubricity without causing fine irregularities on the surface due to its slipperiness.
