Drying occurs when solvents evaporate from the surface of the film,
leaving it tack free. There are four important elements of proper
drying: temperature, humidity, film thickness and airflow. Temperature
affects viscosity, which contributes to film thickness. Humidity affects
the evaporation rate of the solvents. The amount of airflow determines
how much oxygen will crosslink with the finish to initiate curing. High
temperatures, low humidity, thin film thickness and adequate airflow
will all expedite dry time and cure time. If these elements are not
maintained properly, the finish could dry too quickly.
Curing occurs when residual solvents leave the film and it begins
crosslinking with oxygen in the air to develop strength, toughness,
abrasion resistance and chemical resistance. Although most finishes
reach 90% cure in seven days, full cure takes up to thirty days.

NAILED it. The guys at the local industrial Sherwin Williams I go to would probably offer you a job!
