Embodiments of a chemical, methods of applying a chemical, and devices with a coating of a chemical can be used to protect devices from harm, such as for example corrosion, water tensile forces, dust, and oxidation. The device can include a phosphonate-coating, a silane-coating, or both, located on a substrate. The silane-coating can include chemical formula (1), chemical formula (2), or combinations thereof; and the phosphonate-coating can include chemical formula (3): where R1 can be a hydrophobic group; R3 and R5 can be any chemical element or group; r can be a positive integer; and X and Z can each be a bond to the substrate.
