2) Poor adhesion: the hydrophobic material is an intermediate medium through an organic solvent or an adhesive and the like, and is not directly attached to the surface of the substrate, and the intermediate medium is peeled off from the substrate or peeled off from the intermediate medium.
3) Weather resistance is poor: the hydrophobic material is not resistant to ultraviolet irradiation, is easy to age and crack, can fall off in a few months, and has no weather resistance.
4) Dust particle adhesion needs cleaning: the surface of the substrate treated by the hydrophobic material has no effect of splashing fine dust and particles, and even if the substrate is rained or flushed, the substrate needs to be brushed with a cleaning agent regularly.
