The outline of lacquer dewetting or eyeholing on electroplytic tin plate and the results of lacquer flow test were studied.
A small drop of the standard lacquer was flowed on the tin plate to form triangular figure.
The test result was compared with each of ten standard samples to determine the degree of lacquer dewetting on the specimen plate.
The relationship between the lacquer flow test value and actual dewetting by coating was fairly good, although it was sometimes out of order when actual coating was affected by other factors.
Contact angle of lacquer on the specimen plate was measured; however, the relationship between the lacquer flow test value and the contact angle was not always good.
