In this work the surface tension of a polyethylene used in thermal coating, identified as a mixture of low density polyethylene (LDPE) and stearic acid, was measured as a function of temperature for temperatures ranging from 120[degrees]C to 150[degrees]C using a pendant drop apparatus. The values were compared to the surface tension of the pure components (low density polyethylene and stearic acid). It was shown that the surface tension of the mixture is higher than the surface tension of the pure components (more than 25%). Surface analysis by Electron Spectroscopy for Chemical Analysis (E.S.C.A.) of the polyethylene used in ...
