  • Publication number: 20200102742
    Abstract: An acoustical ceiling panel is provided having a core with a front face and a back face composed of air laid mineral fibers and an aqueous binder. The aqueous binder includes a first component in the form of one or more carbohydrates, and a second component in the form of one or more compounds selected from sulfamic acid, derivatives of sulfamic acid, and any salts thereof, ammonia and hypophosphorous acid. A formaldehyde-free first fleece having a thickness is secured to the front face of the core by powdered adhesive and a formaldehyde-free second fleece having a thickness is secured to the back face of the core by the aqueous binder, with the thickness of the first fleece being greater than the thickness of the second fleece. Paint is applied to the first fleece. The acoustical ceiling panel has formaldehyde emissions of below 8 ?g/m2/h of formaldehyde, preferably below 5 ?g/m2/h, most preferably below 3 ?g/m2/h, in accordance with ISO 16000 for testing aldehyde emissions.
