Водный покрывающий состав может быть нанесен на необработанную гладкую подложку с грунтовкой из политетрафторэтилена, имеющего вязкость расплава выше 105Па•с плюс второй политетрафторэтилен, имеющего вязкость расплава в диапазоне от 102 до 107, при этом вязкость расплава первого типа политетрафторэтилена по меньшей мере в 102 Па•с выше относительно второго типа, чтобы создать градиент концентрации.The aqueous coating composition can be applied to an untreated smooth substrate with a polytetrafluoroethylene primer having a melt viscosity higher than 10 5 Pa · s plus a second polytetrafluoroethylene having a melt viscosity in the range from 10 2 to 10 7 , while the melt viscosity of the first type is polytetrafluoroethylene to 10 2 Pa • s higher relative to the second type to create a concentration gradient.
