Abstract
Composiciones de recubrimiento en polvo de resinas epoxi, con buena duración en almacenamiento y capaces de curarse rápidamente, que se obtiene mezclando dos tipos de resinas epoxi con partículas de carga y una agente de curado. Una resina es del tipo de epiclorhidrina-bisfenol A. La otra resina es un epoxi de epiclorhidrina-bisfenol A modificado con un epoxi-novolac. Se obtienen películas de curado rápido utilizando un agente entrecruzante de resina de poliéter aromático alifático mixto, que contiene grupos hidroxi. El curado es acelerado con un alquilimidazol. Estas composiciones son útiles en el recubrimiento de substratos metálicos, especialmente exterior de tuberías, donde son necesarios un curado rápido, flexibilidad y buena adhesión.
