Resumo

Este artigo visa uniformizar as práticas de conservação de artilharia do século XX exposta em fortes da costa inglesa, identificando um revestimento protetor adequado para a coleção nacional. Amostras com cinco sistemas de revestimento estão a ser envelhecidas artificialmente em laboratório, durante 15 meses, e naturalmente em dois locais costeiros do Reino Unido, durante três anos. O impacto do envelhecimento nas propriedades químicas, físicas, estéticas e de proteção dos revestimentos está a ser medido através de ensaios de adesão e de impacto, colorimetria, FTIR, consumo de oxigénio e EIS. O artigo considera os resultados dos ensaios físicos de três e seis meses de envelhecimento acelerado e de um ano de exposição in situ. Com base nos critérios estabelecidos e neste conjunto de dados, o sistema com melhor desempenho é o revestimento epoxídico Sherwin Williams 1.
