  • Publication number: 20230109479
    Abstract: A coated non-woven fibrous mat is disclosed comprising a non-woven precursor mat including a plurality of randomly oriented fibers bound by a precursor binder composition, The non-woven fibrous precursor mat has a first major surface and a second major surface opposite to and having a surface roughness greater than the first surface, defining a thickness therebetween. A coating composition is applied to the second major surface of the non-woven precursor mat and substantially uniformly penetrates 5% to less than 30% of the thickness of the non-woven precursor mat. The coating composition comprises a mineral filler and an organic latex binder composition. The coating composition is applied to the non-woven precursor mat in an amount between 1.0 and 10.0 lbs/100 ft2.
