Abstract

PROCEDIMIENTO PARA EL SELLADO SUPERFICIAL DE PIEZAS MOLDEADAS CONSTITUIDAS A BASE DE ELASTOMEROS DE POLIURETANO. SE SOMETE A LA PIEZA DE ELASTOMERO DE POLIURETANO A UN PROCESO DE RECUBRIMIENTO, POR INMERSION O POR PULVERIZACION, CON UNA LACA DE POLIURETANO DE UNO O DOS COMPONENTES, O CON UNA SOLUCION O DISPERSION DE POLIURETANO; A CONTINUACION SE EFECTUA UN PROCESO DE SECADO. OPCIONALMENTE, DICHA CAPA DE RECUBRIMIENTO PUEDE SER EXTENDIDA SOBRE LA SUPERFICIE INTERIOR DEL MOLDE EN EL QUE VA A CONFORMARSE DICHA PIEZA DE ELASTOMERO DE POLIURETANO CON LO QUE, TRAS EL PROCESO DE MOLDEO, SE OBTIENEN PIEZAS YA SELLADAS. LAS PIEZAS SELLADAS DE EMPLEO EN LA INDUSTRIA DE LA AUTOMOCION COMO COMPONENTES AMORTIGUADORES Y PARAGOLPES.
