Abstract

Perfectionnement apporté au procédé du brevet principal pour l'enduction au moule de pièces formées à partir d'une matière à mouler en plaques, après moulage et durcissement jusqu'à une rigidité suffisante pour que la pièce ne soit pas déformée par l'injection de l'enduit dans un espace formé par séparation des deux moitiés du moule, tout en maintenant le moule étanche Ce perfectionnement est caractérisé en ce que la composition d'enduction comprend, en plus de la résine d'ester vinylique et de l'additif anti-retrait, une charge de silicate à structure feuilletée, mica ou talc, qui donne à l'enduit une meilleure adhérence, d'autres charges usuelles pouvant être aussi ajoutées. Application à la peinture d'automobiles.
