As mentioned previously, the vast majority of key residues of AR were nonpolar; it was reasonable to speculate that these residues can form greater van der Waals interactions with hydrophobic ligand and exhibit more favorable nonpolar interaction contribution to the binding free energy.
In typical three-layer factory-applied coatings, a fusion bonded epoxy provides excellent resistance to corrosion, and a copolymer, which is either a chemically modified PE or PP depending on the top layer, bonds the nonpolar PE or PP outer layer to the polar epoxy.
