The term “alkyd” is derived from "alcohol" and "acid," referencing the resin that gives these coatings their film-forming properties. Although not as durable as polyurethanes and epoxies, alkyd coatings are resilient and particularly effective against moisture. They are commonly used on both interior and exterior structures, including those that are underground and underwater.
The formulation of alkyd coatings can be adjusted to suit various conditions, allowing for customized performance. However, alkyds take longer to dry compared to other coatings, as they require exposure to oxygen to cure. To expedite the drying process, contractors may apply heat to accelerate the chemical curing reaction.
