Alkyds are made with an alkyd resin binder that has been modified with a nonyellowing drying oil for optimum color retention, excellent durability, and rapid drying time. Alkyds' main advantage over oil paints is that they may dry to the touch in 12-48 hours, and paintings employing fairly thin applications may be ready to varnish in as little as 30 days. Drying times and gloss level vary by brand. Use alkyds with an alkyd medium or other traditional Oil Painting Mediums. Clean up with mineral spirits.
