The present invention relates to an anti-tack formulation of high solids content that uses effective amounts of a fine particle size talc, a water soluble cationic polymer, one or more nonionic surfactants, and one or more alkali metal fatty acid soaps. The high solids content anti-tack formulation is capable of being easily shipped to a customer's location and is stable and easily pumped after shipment to a customer. The high solids content anti-tack formulation can be diluted to a low solids content formulation for use in anti-tack applications, particularly rubber slab dipping applications. The anti-tack formulation provides improved anti-tack performance when coating uncured rubber products. L'invention concerne une formulation anti-adhérence à haute teneur en solides utilisant des quantités efficaces d'un talc à petite taille de particule, d'un polymère cationique hydrosoluble, d'au moins un tensioactif non ionique et d'au moins un savon d'acide gras de métal alcalin. La formulation anti-adhérence à haute teneur en solides selon l'invention peut être facilement expédiée à l'endroit où se trouve un client, et elle est stable et peut être facilement pompée après l'expédition au client. La formulation anti-adhérence à haute teneur en solides peut être diluée pour obtenir une formulation à faible teneur en solides destinée à être utilisée dans des applications anti-adhérence, en particulier des applications de trempage de plaques en caoutchouc. La formulation anti-adhérence selon l'invention offre des performances anti-adhérence améliorées lors du revêtement de produits en caoutchouc non vulcanisé.
