Abstract: The sealed state and moisture volatilization of a water-borne sealer for wood furniture using maple-veneered panels were determined for five different natural environments. Drying ability in different conditions was analyzed and the sealed state was studied with a scanning electron microscope （SEM）. The dried-water weight for moisture and the drying rate were measured using a water weight-loss method. Results showed that the drying condition greatly influenced the sealed state and drying speed. After drying for 30 min with drying conditions of temperatures of 11.2－13.2 ℃，relative humidity of 21.1%－23.4%，and air velocity of 0.04－0.05 ms－1；the moisture evaporation rate of the sealer was 16.48%. However，with temperatures of 18.9－19.1 ℃，relative humidity of 54.1%－55.6%，and air velocity of 0.03－0.15 ms－1，the evaporation rate was 2.23%. Thus，the sealed state with 11.2－13.2 ℃ was better than with 18.9－19.1 ℃.［Ch，6 fig. 19 ref.］
