Abstract: These and other objects are satisfied by the present invention, which as a first aspect provides a cementitious composition with non-stick properties. The composition comprises a calcium aluminate cement matrix, a mineral filler, a polymer binding agent, and a fluoropolymer. The composition may optionally include other components which enhance certain mechanical, chemical, or processing characteristics of the composition, such as hardeners, defoamers, lubricants, accelerators, reaction inhibitors, suspension agents, and heat transfer enhancers.
Abstract: A novel cementitious composition based on calcium aluminate and suitable for use in molds is provided. The composition comprises a calcium aluminate powder base, at least one particulate inorganic filler, a latex binding agent chemically compatible with said calcium aluminate powder, at least one dispersing agent, an initiator which initiates the binding of said calcium aluminate powder to said inorganic filler at pH values between 6.5 and 8.0, at least one surface hardness agent comprising an alkyl-aryl sulfonate compound or salt thereof or an aryl sulfonate compound or salt thereof, a polymer salt surface gloss agent, and at least one metal or non-metal oxide wetting agent. A process for producing the composition and a process of applying the composition to form it into a desired shape are also provided.
