How does the drying time of water-based alkyd enamel differ from that of conventional alkyd enamel?

　　The drying time of water-based alkyd enamel paint is typically shorter than that of conventional alkyd enamel paint.

　　Waterborne alkyd enamel uses water as its solvent; during the drying process, it primarily relies on the evaporation of moisture and is significantly influenced by ambient humidity. However, overall, its drying speed is relatively fast. Under conditions of 25℃ and 50% relative humidity, the surface-drying time for waterborne alkyd enamel typically ranges from 0.5 hours, while the full-drying time is about 12 hours.

　　Ordinary alkyd enamel paints are typically oil-based. Their drying process involves the evaporation of solvents and the oxidative crosslinking reaction of the resin, resulting in a relatively slow drying rate. At 25°C, the surface-drying time for ordinary alkyd enamel paints is ≤4 hours, and the full-drying time is ≤24 hours. Moreover, in environments with high humidity, the drying time of ordinary alkyd enamel paints will be significantly prolonged, while water...
