Abstract

Mejoras introducidas en un método de recubrimiento de una pieza realizada a partir de un compuesto de moldeo laminar después de que la pieza ha sido formada y curada hasta un estado suficientemente rígido para que la pieza no sea deformada por la inyección de la composición de recubrimiento en un espacio formado separando las dos mitades el mole mientras que se mantiene el molde en condiciones de hermeticidad, caracterizadas porque consisten en inyectar una composición de recubrimiento constituida por una mezcla de un aditivo de pequeña contracción y una resina de éster vinílico formada por reacción de una resina poliepóxida con un ácido monocarboxílico insaturado.
