SCRIM ATTACHMENT SYSTEM

摘要

The present invention is directed to ceiling panels formed from a porous scrim that is coupled to an acoustical substrate using a scrim attachment system that includes an adhesive.

主权项

1. A ceiling panel comprising:
an acoustical substrate comprising substrate fibers and having a first major substrate surface and a second major substrate surface opposite the first major substrate surface, the acoustical substrate having a first air flow resistance measured through the acoustical substrate from the first major substrate surface to the second major substrate surface; a porous scrim comprising scrim fibers and having a first major scrim surface and a second major scrim surface opposite the first major scrim surface; a dry-state adhesive that is solid at room temperature and comprises less than 5 wt. % of water, the dry-state adhesive adhering the first major substrate surface of the acoustical substrate to the second major scrim surface of the porous scrim, the dry-state adhesive comprising a gel-forming film-forming polymer; and wherein the dry-state adhesive is present in an amount that ranges from 4 g/m2 to 13 g/m2.
