The present disclosure embraces cementitious panels, and systems and methods of manufacturing cementitious panels. An exemplary cementitious panel includes a cementitious core material, a plurality of sheets of facing material surrounding the cementitious core material, and a radiation-cured adhesive. An exemplary method of manufacturing a cementitious panel includes conveying a slurry of cementitious core material and a plurality of sheets of facing material, applying a radiation-curable adhesive to at least one of the sheets of facing material, forming a continuous length of cementitious panel material, at least partly curing the radiation-curable adhesive with one or more beams of radiation emitting from one or more radiation-emitting devices, and cutting the continuous length of cementitious panel material laterally to a desired length, providing a cementitious panel.

An adhesive binder composition for adhering a paper sheet to a gypsum article with a gypsum layer having at least one paper sheet on a major surface thereof. The adhesive binder composition includes a polymeric adhesive and at least one surfactant. The adhesive binder composition resides at a boundary between the gypsum layer and the paper sheet.

Coating and binder compositions for gypsum boards

A gypsum wallboard suitable for Level 4 finishing having a coated non-woven first glass fiber mat facing material on one major surface and an optionally coated second glass fiber mat where on the other major surface. The first glass fiber mat has a majority of fibers of a nominal fiber diameter between 8 and 11 microns and a fiber length between &#xbc; and &#xbe; inch and has a basis weight between about 1.7 lb./100 ft.and about 2.0 lb./100; the second glass fiber mat has a majority of fibers of a nominal fiber diameter of at least 13 microns but no greater than about 16 microns and a fiber length between &#xbe; and 1 inch and has a basis weight between about 1.8 lb./100 ft.and about 2.2 lb./100, and wherein the fibers in both of the non-woven glass fiber mats are bound together with an acrylic-type adhesive binder.
