Abstract: 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 generates a micro-flocculated pigment dispersion that can be subsequently 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.
