Silicon-Based Inorganic Zinc-Rich Coatings

Other types of binders include qxtxy esters and silicon-based inorganic zinc-rich coatings. 

Despite their name, epoxy esters are not really epoxies. Applanan, in fact, writes that epoxy esters are best described as an epoxy-modified alkyd [20]. They are made by nfixing an epoxy resin with either an oil (drying or vegetable) or a drying oil acid. The epoxy resin does not crosslink in the manner of conventional epoxies. Instead, the resin and oil or drying oil acid are subjected to high tanperature, 240°C to 260°C and an inert atmosphere to induce an esterification reaction. The result is a binder that cures by oxidation and can therefore be formulated into one-component paints. 

Epoxy esters generally possess adhesion, chemical and UV resistance, and corrosion protection properties that are somewhere between those of alkyds and epoxies [21]. They also exhibit resistance to splashing of gasoline and other petroleum fuels and are therefore commonly used to paint machinery [18].
