Hydrophobicity transfer

from Wikipedia, the free encyclopedia

Hydrophobicity transfer describes the property of polymeric insulating materials made of silicone to transfer their hydrophobicity to the surface of foreign layers such as pollution layers after a certain time . This means that the soiled insulation can have the same hydrophobicity as the unpolluted one. The hydrophobicity transfer thus significantly influences the foreign layer behavior of outdoor insulation and is therefore crucial for its design. The diffusion of low molecular weight components of the insulating material is responsible for the transfer of the hydrophobicity in layers of pollution . As a result, a small amount of silicone substance is lost.
