Little is 5～15 microns.This utility model can not only effective waterproof, more the moisture on surface can be made to shrink using its waterproof and dampproof property
For pearl, and the drying of convenient holding surface and cleaning.And due to material behavior, after the completion of coating can't self is conductive,
But each metallic contact can't become thickness to cause the phenomenons such as loose contact or open circuit because of coating.Hydrophobic angle in coating exists
Between 110-120 degree, the globule slidably although water resistance is strengthened, but can not carry out resistance to water Soak Test,
Cannot judge whether life-time service still has reliable water resistance.
