| Summary: | This research investigated the usage of cuprous oxide powder as filler for epoxy in marine coating industries. The basic
formulation consist of cuprous oxide powder, epoxy pre-polymer, and the curing agent. The main manipulation variable in
this research is the quantity of cuprous oxide added into the epoxy resin, which varies from 2, 5, 7, 9, and 11 per hundred
gram of epoxy resin (phr). Polyether (amine) was used as the curing agent at equivalent molar ratio. Mechanical stirring was
used to achieve dispersion. The samples were cured at room temperature for one week before characterization. Differential
scanning calorimetry (DSC), scanning electron microscopy (SEM), infrared spectroscopy (FTIR), X-ray diffraction (XRD),
drop shape, water and brine absorption, hardness, and abrasion analysis were used. Drop shape analysis exhibited the
hydrophobicity of the surfaces. According to water and brine absorption test that was carried out, it is found that the
unmodified epoxy sample has the lowest absorption of water and brine. The composite coating, which underwent abrasion
test, exhibited increasing hydrophobicity of the surface directed on the electrical wave generator in 5 days. |
