Drying Properties of Cashew Film by Thinning Conditions

This work was done to investigate problems of cashew coating in a wooden-art industry such as ritual vessels and to improve a curing property of cashew film. The main problem in the cashew coating industry was a small-scale business, insufficiency of facilities, lack of knowledge about cashew resin and painting, and lack of a technology of productivity improvement by accelerated drying time of cashew film. In present, cashew coating for ritual vessels mostly used the petroleum. as a thinner. The time of set to touch of cashew film thinning with petroleum on glass plates was increased with the increasement of the thinning proportion, but retarded from 3 to 11 times compared to that of an exclusive thinner according to thinning level. The addition of 20% aceton to petroleum contributed to the high reduction rate up to about 60% at the thinning level of 100%, which was effective to accelerate the drying time of cashew film. Even though only the petroleum or the petroleum-aceton(20%) mixture was used as a thinner, it did not exhibit any distinguishable differences in crack and appearance of cashew-film coated on Fraxinus rhynchophylla after 5 cycles of soak under the vacuum-drying treatment.
