Abstract

"PROCESSOS MULTI-ESTáGIOS PARA REVESTIR SUBSTRATOS COM CAMADA BASE LìQUIDA E CAMADA SUPERIOR EM Pó". Processos para revestir substratos metálicos ou poliméricos são providos os quais incluem as etapas de: (a) aplicar uma composição líquida de camada base a uma superfície do substrato; (b) expor a composição de camada base a ar tendo uma temperatura variando de cerca de 10<198>C a cerca de 50>198>C por um período de pelo menos cerca de 5 minutos para volatilizar pelo menos uma porção de material volátil da composição líquida de camada base, a velocidade do ar em uma superfície da composição de camada base sendo menor que cerca de 0,5 metro por segundo; (c) aplicar radiação infravermelha e ar quente simultaneamente à composição de camada base por um período de pelo menos cerca de 2 minutos, a velocidade do ar na superficie da composição de camada base sendo menor que cerca de 4 metros por segundo, a temperatura do substrato metálico sendo aumentada em uma taxa variando de cerca de 0,4<198>C por segundo a cerca de 1,2<198>C por segundo para alcançar uma temperatura de pico do substrato variando de cerca de 120<198>C cerca de 165<198>C, tal que uma camada base seca seja formada sobre a superfície do substrato; e (d) aplicar uma composição de camada superior sobre a camada base seca.
