Abstract: A multi layer composite having oil and grease resistance comprising: a) a paper or paperboard substrate, b) a base coat on a surface of said substrate comprising a first polymer selected from the group consisting of film forming natural and synthetic polymers in the substantial absence of a mineral pigment filler, and c) a top coat on a surface of said base coat, said top coat comprising a continuous polymer phase comprising one or more film forming synthetic polymers having dispersed therein at least one platy mineral pigment and at least one non-platy mineral pigment. This invention also relates to a method of making the composite and articles of manufacture fabricated totally or in part from the composite of this invention where oil and grease resistance is required or desired, such as container, bags and wraps for packaging oily or greasy materials such as animal and human food.

Abstract: A novel organofunctional silane for use in binding agent compositions employed in foundry sands and the cores and molds made therefrom. The novel organofunctional silane is characterized in that it contains at least one sterically hindered hydrocarbon group and has attached to the silicon atom a nitrogen containing group via a carbon-silicon bond.
