“…The cyclic corrosion test in an environment with a NaCl mist was based on ISO 7253. In this test the test panels were exposed to the mist of a neutral 5% NaCl solution at 36°C for 10 hours (1 st cycle stage) and to condensing water at 40°C for 1 hour (2 nd cycle stage), followed by drying at 23°C for 1 hour (3 rd cycle stage) [36]. After the corrosion tests the paints were evaluated by methods derived from ASTM D 714-87, ASTM D 610 and ASTM D 1654-92 standards [36].…”

“…In this test the test panels were exposed to the mist of a neutral 5% NaCl solution at 36°C for 10 hours (1 st cycle stage) and to condensing water at 40°C for 1 hour (2 nd cycle stage), followed by drying at 23°C for 1 hour (3 rd cycle stage) [36]. After the corrosion tests the paints were evaluated by methods derived from ASTM D 714-87, ASTM D 610 and ASTM D 1654-92 standards [36]. The following corrosion phenomena were assessed: formation of blisters on the fi lm (their size and number); extent of corrosion across in the substrate metal surface observed after removing the fi lm (percent area fraction affected); extent of propagation (in mm) of corrosion of the substrate metal near a cut made in the fi lm, observed after removing the fi lm; and formation of blisters on the fi lm near the cut made in it (their size and number).…”

“…A Figura 2 apresenta a reação de obtenção de uma resina epóxi. [26] Para que ocorra a cura da resina epóxi com a formação de um filme protetor, é necessária a adição de agentes de cura à resina antes de sua aplicação. Estes agentes de cura ou de reticulação irão reagir quimicamente, através de uma reação de polimerização, com os grupos reativos da resina epóxi.…”

“…Tabela 16 -Absorções características dos grupos funcionais presentes nas estruturas da resina éster de epóxi e da poli(ureia-formaldeído-melamina) [26,[116][117][118][119] Grupos funcionais Número de onda cm , por conta do estiramento da ligação C-N presente nos compostos derivados da ureia [118] e também para compostos melamínicos [119]. Como a parede formada é muito fina, a visualização de seus componentes no espectro de FTIR pode ficar prejudicada, já que algumas destas regiões de absorção coincidem com as regiões de absorção da resina éster de epóxi, principalmente o das ligações C=O que são ligações caraterísticas tanto da resina quanto da parede polimérica das microcápsulas.…”
