O revestimento em p\u00f3 \u00e9 um processo em que uma tinta em p\u00f3 seca (um pol\u00edmero termopl\u00e1stico ou termoendurec\u00edvel) \u00e9 aplicada a uma superf\u00edcie met\u00e1lica atrav\u00e9s de aplica\u00e7\u00e3o eletrost\u00e1tica. Ao contr\u00e1rio da tinta l\u00edquida tradicional, o revestimento em p\u00f3 n\u00e3o necessita de um solvente para manter o aglutinante e o material de enchimento da tinta em suspens\u00e3o l\u00edquida. Isto permite a aplica\u00e7\u00e3o de revestimentos mais espessos sem escorrimento ou flacidez e, consequentemente, os revestimentos s\u00e3o tamb\u00e9m mais resistentes.<\/p>

O processo de revestimento a p\u00f3 come\u00e7a por ligar eletricamente \u00e0 terra a pe\u00e7a a pintar, o que lhe confere uma carga l\u00edquida negativa. Ap\u00f3s a liga\u00e7\u00e3o \u00e0 terra, a tinta \u00e9 pulverizada na pe\u00e7a utilizando uma pistola corona, que aplica uma carga positiva ao p\u00f3. A polariza\u00e7\u00e3o dos dois componentes faz com que o p\u00f3 adira ao metal, onde permanecer\u00e1 enquanto n\u00e3o for perturbado.<\/p>

Depois de o p\u00f3 ter atingido uma espessura especificada na pe\u00e7a, \u00e9 curado numa pel\u00edcula polim\u00e9rica utilizando temperaturas elevadas (~200\u00b0C), como num forno de convec\u00e7\u00e3o. Os pol\u00edmeros termoendurec\u00edveis reticulam durante o processo de cura para melhorar o desempenho, mas as variedades termopl\u00e1sticas simplesmente fluem enquanto aquecidas para formar o revestimento final.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
