Abstract

Un procedimiento para preparar un virador en polvo que adquiere una carga negativa por contacto triboeléctrico con partículas portadoras metálicas, cuyo virador en polvo contiene partículas coloreadas fusibles que comprenden un constituyente de resina termoplástico aislante y, si se desea, un agente de control de la polaridad que actúa negativamente, caracterizado porque la mayor parte y de preferencia sustancialmente todo el constituyente de resina termoplástico aislante se prepara bloqueando al menos el 50% del número total de grupos epoxi iniciales de una o más resinas epoxi.
