Abstract

Cet adjuvant comprend un épaississant à dissolution retardée, tel que de l'amidon, un rétenteur d'eau tel que de la méthylcellulose, un retardateur de prise tel que de la gélatine de aux et, éventuellement, un agent adhésif constitué par des colles d'os lyophylisées. Cet adjuvant entrant pour 1 à 2 % dans la composition d'un plâtre conduit à un mélange dont l'évolution de la viscosité en fonction du temps montre une plage de travail d'une durée importante.
