Effects of dehumidification drying environment on drying speed of one component waterborne wood top coating

One component waterborne wood top coating is dried by dehumidification drying method, hard drying time is decreasing with the increasing air temperature and velocity and decreasing relative humidity. Air velocity is extremely significant to hard drying time. The difference of hard drying time is significant when the difference was 5min and above, and it is extremely significant when the difference is 10 min and above, which are useful to judge the hard time in practice.
