발수성은 코팅막 상에 물방울을 떨어뜨려 물방울의 퍼짐 정도로 측정하였고, 도포성은 코팅 조성물이 기재 상에 얼룩을 만들지 않고 균일하게 도포되는 정도를 측정하였다. The water repellency was measured by dropping water droplets on the coating film to measure the degree of spread of the water droplets, and the applicability was measured to the degree that the coating composition was uniformly applied without making a stain on the substrate.
