| Résumé : |
In the past major focus during construction and maintenance of industrial plant was primarily on process equipement and the material of construction. The concrete structure and flooring was considered less critical. However in current scenario, floorings in plant are integral part of many operations. Limitations of concrete flooring are dust accumulation, porosity, cracks, alkalinity, microbial growth, laitance, efflorescence, and poor chemical resistance. To overcome these limitations and provide a sound surface, various protective coatings are in use. Protective coating in majority are self-levelling floor coatings based on epoxy and polyurethane chemistry. Self-levelling epoxy flooring is known for its high adhesion, hardness and initial gloss, however, poor in flexibility, scratch resistance and gloss retention. The advantage of polyurethane coating over epoxy coating is because of its flexibility, scratch resistance and durability. |
