The present disclosure relates generally to a water-resistant gypsum board including a gypsum core with a first major surface and a second, opposing major surface; a first liner having a first major surface and a second, opposing major surface, the first liner comprising at at least the first major surface thereof a condensation product of a polysiloxane comprising at least one silanol, the first major surface of the first liner being disposed against the first major surface of the gypsum core; and a second liner having a first major surface and a second, opposing major surface, the first major surface of the second liner being disposed against the second major surface of the gypsum core.

A coated paperboard is disclosed which includes a printable coating containing substantially no fluorochemical or wax in which the coated paperboard is fully compostable as well as repulpable, and exhibits no tendency toward blocking. The coating may be a multiple layer coating.

A coated paperboard is disclosed which includes a barrier coating containing substantially no fluorochemical or wax, exhibiting good resistance to oil and grease, no tendency toward blocking, the coated paperboard being fully repulpable as well as compostable. The coated paperboard may further have a printable coating on a surface opposite from the barrier coating.
