Web10 sep. 2024 · Petroleum-based paraffin wax is the main hydrophobic agent for wood-based panels, which can be applied purely in a melted form or as water-based dispersions [ 3, 4 ]. In the latter form, paraffin wax, so called hydrowax, can also be added to the resin, and thus injected into the blowline [ 5 ]. WebPTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware.
