Abstract
Procedimiento para preparar un polvo de virador que adquiere una carga positiva por contacto triboeléctrico con partículas de soporte metálicas, el cual polvo de virador contiene partículas fusibles, coloreadas, que comprenden un constituyente de resina termoplástica, caracterizado porque la parte principal del constituyente de resina termoplástica se produce bloqueando al menos 50% del número total de grupos epoxi iniciales de una o más resinas epoxi, en parte, pero al menos en 5%, por reacción química con un ácido carboxílico o fenol monofuncional y en parte por reacción intermolecular con los grupos hidroxílicos de la resina o resinas epoxi y/o por reacción con un endurecedor epoxi bifuncional y porque durante la reacción de bloqueo o después de ella, se añaden una epoxiamina, que es el producto de reacción de una resina epoxi con una amina primaria o secundaria, que tiene un valor pKa superior a 3, material colorante, y si se desea, una resina fenoxi y/u otros ingredientes, y se mezclanhomogéneamente entre sí.
