SOME EVALUATION AND RESEARCH RESULTS OF MECHANICAL PROPERTIES AND SEAWATER RESISTANCE OF EPOXY COATINGS ON POROUS MATERIALS

Abstract

Due to outstanding properties of mechanical properties, resistance to chemicals, seawater etc., epoxy
materials are used effectively in the fields of paints, glues, composites, bulk materials, etc., and in many
other specialized sectors such as transportation, aerospace. Within the scope of this research, the
efficiency of epoxy materials is evaluated in the marine environment with the main purpose of improving
the resistance capacity of seawater intrusion and also increasing the mechanical properties of porous
materials in quick assembly works in the sea and on islands. This research presents some research results
on the effectiveness of epoxy coatings on expanded polystyrene foam, extruded polystyrene foam and
polyurethane foam. The achieved results showed that, when coating foam panels with the quantity from
460g/m2 to 570g/m2 by epoxy resin, the level of seawater resistance reaches 97.7%, the compressive
strength of the porous materials when coating epoxy reaches 1219.3kJ/m2.
