Hydrophobic mobility varies slightly with environment, temperature, characteristics of pollution, amount of pollution and air pressure intensity, which is difficult to change. However, the constituent materials of the coating itself greatly enhance the water migration.
Since the small molecule released by RTV/PRTV during vulcanization is a kind of siloxane in the form of silicone oil, these siloxanes are produced by the small molecule maintaining the thermodynamic equilibrium state inside the silicone rubber.
These small siloxane molecules are strongly hydrophobic. When there is dirt on the paint surface, small molecules diffuse in the dirt layer and on the surface, forming a network of small molecules, deeply burying, wrapping, and transferring hydrophobicity to the dust surface.
