Abstract
Procedimiento para evitar el pegado de una resina de poliéster insaturado curable al molde que la contiene caracterizado porque comprende las etapas de: (a) colocar una hoja de desmoldeo contra la superficie del molde de modo que se sitúe una capa de desmoldeo más alejado de la superficie del molde, comprendiendo la hoja de desmoldeo una película termoplástica auto-soportante revestida, en una o ambas superficies de la misma, con una capa de desmoldeo contínua que comprende un interpolímero formador de película de estireno o sus derivados con una cantidad de uno o más cronoméros etilénicamente eficaces para hacer que el interpolímero sea formador de película, teniendo la capa o capas de desmoldeo un espesor no superior a 0,5 micras; (b) aplicar una resina de poliéster insaturado curable a la capa de desmoldeo; (c) permitir o causar el curado de la resina; y (d) separar las hojas de desmoldeo de la resina curada, siendo la película termoplástica de la hoja de desmoldeo dimensionalmente estable bajo las condiciones de curado de la resina.
