Abstract
Described herein is a coated acoustic building material comprising a body comprising a first major surface opposite a second major surface; a coating having an upper surface opposite a lower surface, the lower surface of the coating facing the first major surface of the body, the coating comprising: polymeric binder having a glass transition temperature less than 0° C.; and a filler; wherein the coating is present as coalesced particles atop the first major surface in an amount ranging from about 210 g/m2 to about 1,300 g/m2.

A coated acoustic building material comprising:
- a body comprising a first major surface opposite a second major surface;
- a coating having an upper surface opposite a lower surface, the lower surface of the coating facing the first major surface of the body, the coating comprising:
- polymeric binder having a glass transition temperature less than 0° C.;
- and
- a filler;
- wherein the coating is present as coalesced particles atop the first major surface in an amount ranging from about 210 g/m2 to about 1,300 g/m2.
An acoustic building system comprising:
- a first building panel comprising a first major surface defined by a first perimeter, and a second building panel comprising a second major surface defined by a second perimeter, at least a first portion of the first perimeter being immediately adjacent to a second portion of the second perimeter, whereby a seam exists between the first portion and the second portion;
- a coating applied to the first major surface and the second major surface such that the coating covers at least a portion of the seam;
- wherein the coating comprises polymeric binder having a glass transition temperature less than 0° C. and a filler, and wherein the coating is present as coalesced particles atop the first major surface in an amount ranging from about 210 g/m2 to about 1,300 g/m2.
A coated acoustic building material comprising:
- a non-woven layer having an upper surface opposite a lower surface;
- a coating having an upper surface opposite a lower surface, the lower surface of the coating facing the upper surface of the non-woven layer, the coating comprising:
- polymeric binder having a glass transition temperature less than −20° C.;
- and
- a filler;
- wherein the coating is present as coalesced particles atop the upper surface of the non- woven layer and an airflow resistance ranges from about 40 mks rayls to about 7,500 mks rayls as measured between the lower surface of the non-woven layer and the upper surface of the coating.
